Thanks, that's exactly what I was looking for. Going with the Denso's...Thanks all for the replies.

I have access to an OBD-II scanner...the codes are definitely upstream and downstream O2 sensors (specifically bank 1 and bank 2 oxygen sensor malfunction, which translates to upstream and downstream O2 sensors since the 420a only has 2 oxygen sensors). I don't remember the specific code...

Definitely no. Too many possibilities of that car being a money pit, and if you're running on a limited budget (like it sounds from your original post), this is definitely not the car for you. There are tons of 420a's in decent shape available for around the same price...but it sounds to me...

Looking for some O.E. O2 sensors for my 420A, but not a huge fan of Bosch. The Denso ones look pretty reasonably priced on autozone.com, but I haven't had any sort of experience with these (durability, longevity, etc.). I guess what I'm asking is if anyone here knows a good place to get a...

Really wish I'd asked this question before I went and bought (and prepped) the new Saturn alternator...good info in this thread guys. And I have to ask the same question as VelocitàPaola, where in the world can you find a new alternator for the 420a for 80-90 bucks? The Saturn alternator...

Thanks for the answers guys...I was looking for a way to keep a stronger charge in my car's battery (I run a system with a 1000w amp and two 12's, but never installed a capacitor...), looks to me like the better way to go would be to just fork out the money for a good capacitor and call it a...

I have a 99 GS with the 420A motor...I want to do the Saturn alternator swap (already have the right Saturn alternator, have ground it down, and am ready to install). I have heard though from some people that the swap can only be done on the 4g63? Someone please give me a straight answer...any...

My sarcasm meter must be broken on my laptop again. I probably need to get that fixed. :thumb:

At least you tried...I didn't mean to be so discouraging in my last reply, but I also wanted to give some relevant advice based on my own knowledge/experiences. It's a tough situation, no doubt about it, and I do hope you get the car sold and can afford to get yourself a replacement vehicle to...

Bank thing is probably a no-go. You said you haven't been at your job very long (banks prefer people who have been at their job for a few years...stability), you're young, which probably means no credit history (which is actually worse than having a bad credit history, believe it or not). 19...

*retardedThe majority of this thread was written back in 2003-2004, when our cars were much closer to new and consequently a little bit more expensive (with a much higher resale value I might add). Taking that into consideration, I don't understand your logic here, what you're saying is that...

You seriously deserve to win some sort of award for dedication to your DSM...the problems you have overcome with your little 420A would have sent most of our cars to the crusher already. I'm watching this thread to see what the outcome of this is...best of luck!

Hit some of the basics...clean the throttle body and Idle Air Controller (super easy to remove and clean, should only take a couple of minutes), and take the EGR off and clean the heck out of it (carb cleaner will work, but be prepared to use at least an entire can, and also be prepared to see a...

No sweat...what ended up solving the problem?

Check the coil next. You'll need another person to help with this (someone to turn the key while you're holding the plug). Simple to do, follow the instructions from here (just ignore the bench test thing and follow the rest of the directions):How To Test Your Coil - Ignition Coil Testing -...

Whoa..."oil leak from the main frame"? Somebody is having some fun with you, and from the sound of it, trying to separate you from your money in the process. There is absolutely no shame in not knowing how stuff works (so long as you don't try to "fake the funk" about it), just be honest and...

No problem, glad to help. I'm not sure how good that keyless setup is that you posted, I personally have no experience with it, but so long as the kit contains a receiver, the proper wiring harness (or a good set of instructions), and remotes, it should be fine. Do some research before...

Call into your local Mitsubishi dealership and give them the VIN, they will be able to look up and see whether or not your car came with keyless entry. If the dealership tells you your car has it, you may still want to do a quick check to make sure the receiver hasn't been removed somewhere...

Those back flush kits are great (and like Locke says, cheap), and I recommend installing one on the car, as it gives you a handy way to insure you're getting that crud out of the block when you change coolant (corrosion, etc.). They're not really necessary if you flush your system correctly...

When you flushed the coolant, did you backflush the whole system or did you just flush the radiator?

No, you may be on to something, and I will definitely confirm this morning. Problem is, I don't have the third, rear window mounted brake light, just an open (dangling in the trunk) socket to hold a bulb...for the life of me I can't figure out why, but the previous owner must not have liked...

Thanks for the heads up on that thread...I'll check it out and see if it helps solve the tail light issue...

From the battery, I get ~ 13V, and the battery seems to be charging just fine. I don't have a voltmeter gauge in the car (still in the "fix everything" stage of pre-modification for this car...I will NOT spend a dime on upgrades until this thing has proven itself to be a reliable DD!)...

Thanks for the quick reply Locke...Today is the first day the tail light issue happened. All the other times I have experienced the electrical surge, the tail lights acted normal (turned off when I turned off the light switch). While I'm DEFINITELY going to follow your advice and keep the...

Ok, never before in my life have I ever encountered an electrical issue as strange as this.The car shuts down randomly while I am driving...I mean completely shuts itself off (motor, radio, everything). It has been immediately cutting itself back on up until lately (like it will shut...

The EGR valve recirculates hot, dirty air back into your motor as a way of cutting down on emissions. The problem is, it dumps all that carbon back into the motor as well. Blocking off the EGR will keep your intake much cleaner, which is really the only true benefit you gain from blocking it...

The EGR can definitely affect the motor at idle. It is supposed to be closed at idle, so if it is faulty and is actually open at idle (a filthy EGR can cause this to happen), it'll act like a huge vacuum leak, and cause some of the issues you mentioned. Far too many times on these forums I...

I went back and checked the thermostat again, just to rule it out as a possible culprit. I boiled it on the stove, it opened like it was supposed to. I didn't think it would be the problem though, because it is relatively new (only a few months old), and my upper radiator hose was getting hot...

After a lot of searching, I came across this thread:Team 2GNT Forum - Viewing topic #127178 - EGR Blockoff Q'sNow I haven't done this mod myself, so I can't tell you whether or not it works, but I am definitely going to give it a try (and will update this thread when I do). Might be...

Glad to be of help. Aren't you glad you took off the EGR now, after seeing all that muck come out of it?:thumb:

OK, here is a little bit of background on the problem;Car overheated the other day. It was in my driveway, I had just come out and started it because I hadn't driven it in a couple of days. I let it run for a few minutes while I was doing something else, I came back to it and it was...

I would take it off to clean it, it's much easier, isn't complicated to get it off, and this way you're not blowing all that carbon back into your motor (causing more problems).Blocking the EGR will give you a CEL (I have heard there are ways around that, but haven't found any yet myself...

I used carb cleaner last time I had my EGR off, it did a pretty good job. Had to use the whole can on it though.

Before you start taking stuff apart, look for obvious stuff on the tires, like chunks of tread missing, bulges, flat spots and uneven tread wear. How old are the tires? When was the last time you rotated them? Are they inflated properly (and evenly)? Always start with the basics first!

Seriously, that took some real dedication. Much respect to you for taking on a project of that size, and saving that car from the grave. Hope you get years worth of enjoyment out of it after all your hard work!

There is a pretty good write up on it here: http://www.dsmtuners.com/forums/articles-turbo-system-intercooler/169435-boost-leak-test-how-boostpro-net-tester.htmlI would recommend using a spray bottle with soapy water to help find small leaks too. Hope this helps.

Sounds like you may have found a couple of bad relays. You can test them to make sure, follow the instructions here: How to Test a Car Relay | eHow.comProbably a safe bet to go ahead and replace them though. And I would definitely recommend getting the right sized battery, don't take any...

Limp mode is designed to let you run the car without doing further damage, so you should be fine. I just wouldn't take it on the highways!

I've seen limp mode without a CEL before (long story short...I was a dumbass and drilled through my main wire harness when running my amp power cable...yeah, I'm an idiot sometimes!), its definitely possible.

You can buy a replacement IAC at Autozone or Advanced or even Napa. Check it before you replace it though, check this thread for how to check it: http://www.dsmtuners.com/forums/420a-bolt-tech/369833-p0505-idle-air-ecu.html

Resolved, it was the IAC. Thanks guys.

Had a similar problem with mine, changed the Idle Air Controller (IAC) and that fixed the problem. I also recommend cleaning the throttle body thoroughly (you can use carb cleaner for this).

A 95 Eclipse is OBDII compliant (or are we talking about a different car than the one in your profile?), get the car to an Autozone or Advanced Auto Parts shop and get them to read the codes for you (they will do this for free). Like Paul said above, check the wires (even if they were put in...

Like nothingfiction said, there is absolutely no substitute for getting under the car and checking things out for yourself. In my experience, you will never find a person so quick to lie to you as the person who just sold you something (especially if it was expensive). Get under there and look...
