The eclipse has been parked for a while..since the 24th, so nothing to update...

home to work:17.5mi@ 53.0mpgTank is at ~94% 162 miles on the odo. __________________

I'd say get a new belt because that one that fell off most likely got damaged when it fell off, not really a problem if it stretches, just any edges it might've gotten when it fell off :)

What I'm saying is the plugs should come pre-gapped if you bought the right plugs. I've never had to gap any plugs after I buy them and never had any issue with loss of power or fuel economy.

...What do you mean you're gapping the plugs? If you have to gap them you most likely don't have the right ones. These cars aren't carb'd.

Just filled up today:684.6 miles and used 14.14 gallons.48.4mpg.On the trip home:76F Tank is at ~115% Odo at 20.2 miles Sg @ 51.0mpgThis tank will last a while as I wont be driving my car much after this week. Some carpooling will be in order. I got my eyes on something and maybe in a...

Tank is at ~43%, Odo is at 458 miles

high idle is killing your mileage. Fix the vacuum leak and that will fix your problem. Time to start hunting. Have you done any work recently on the manifold? Check all the rubber hoses in the engine bay and see if you can find your leak. It might be too small to detect the hissing noise for an...

umm...did you try scanning?? Otherwise you just wasted a ton of cash throwing parts at it like a blind fool (no dis intended). If it doesn't connect, then you most likely need a new ecu, but at least scan it before you piss toss another couple hundred in the trash can.:rolleyes: Get your...

Trust me when I say this, if your fuel filter was bad enough to mess up your fuel trim, I doubt your car would be drivable. You need to list ALL the issues with the car in one place.List them ALL here, and then ONLY then, we can make a somewhat approximate guess as to what your problem is...

170 on a tank? Are you drinking that shit!? I understand you have AWD, but that alone wont bring your mileage down that much.I drove 300 miles and still was at 3/4 tank LEFT. After a fill up, 100 miles usually brings it to the "Full" line.This is just with changing driving habits and MAKING...

Looks like we have a change in the tank slope. I'll have to map this into my calculation:175/(0.22*16.3)=48.8mpg pace.

Tank update:57 degreeshome from work136/(0.14*16.3)Tank is at approx. 86% Odo is at 236 miles.Approx. running tank average is 59.6mpgChrispy:Stop and go traffic as most anyone knows is pretty bad for gas mileage. Shutting down at lights that are longer than 5 seconds (approx...

If the issue resurfaces, try the egr valve. I had the exact same problem. This fixed it.

I just didn't think it needed to go on as long as it did. I'm just calling what I see...I was hoping to see more info, but it's the same stuff repeated in the second page...which I think almost the entire second page can be deleted based on that factor alone.

It's sort of an inside thing :D. Check out the site and you'll get it ;) . The most important thing is that your tires aren't underinflated. If you increase them to the max sidewall, you'll get better handling out of tires with higher A/R or skinny tires. Check out this awesome article ...

The fight is over..you lost...you can go home now. :toobad:

This is difficult to do without a SG II, but here's a tip for accelerating:On the 420A, the throttle position sensor reads from 0 to ~75. Due to an angular offset of the throttle plate, once installed, it only reads from 12 to ~75 and once in an odd while it will show 11.I have the 60mm...

If you want to pay less for gas, go to CleanMPG, An authoritative source on fuel economy and hypermiling. Plenty of Europeans and Americans alike there.That said, Ramsack is right. bastarddsm is wrong. Don't listen to him. You'll be running to buy parts for your car and broken down at the...

equalling more money for the gov't.

Here's an updated graph. Points are updated daily:Based on the numbers from last tank. My estimated gas mileage is currently 55mpg.

Those are EPA figures on a closed loop used to compare all vehicles. Your mileage will vary depending on where and how you drive. If we were all gonna compare numbers, my GS gets 47.75mpg, but that wouldn't be a fair measure since my driving technique is so different.We all drive differently...

This is NY. His VIN is seen as a '99. Along with that, he'll be screwed when the ecu tries to communicate with the rest of the car. This is bad advice.

They can take a long time to reset...Mine was about 2000 miles after the last battery disconnect. You can do it more quickly by running it in a set of parameters to trigger those codes. If you check the manual, it'll tell you when each monitor runs. I could'nt find one...

expect 6-8mpg drop...I guess if you're already launching at 4k around town there's not much further down you can go.Sounds like you'll be at less than 200 miles/tank. (150-175 approx), unless you were just exaggerating. These numbers arent scientific by the way and just represents what I...

I was thinking that might be the difference, however, let me know what I'm missing.Isn't the entire intake manifold manifold and IC filled with that pressurized air? Doesn't that quantitate the volume of air at the given pressure? The only way it makes sense to me is if the smaller "straw"...

In the top right of your picture, right above your battery, I believe you have two relays. One is a fuel pump relay, the other is your ASD relay. I'm 99% sure you're ASD relay is shot. IIRC the one on the right if you're in front of the car, is the ASD relay.I have a switch that disconnects...

By the way, the difference at 15k miles/year between the GST and the GSX (some variations between years) is $600-$800 depending on the price of gas and year of the car. I don't think you'll notice the difference with the year that much.I sometimes wish I had awd. 1st gear in my N/T is...

I'm a tad bit confused by your post. Let me see if I can clear this up.The GST Hatch gets the best overall gas mileage of all variations of the Eclipse at 24mpgAll GSX's get the same 20mpg (spyder or hatch).I was adding that the non turbo 420a actually has a lower rating on the epa. It's...

I've read this a couple times, but could you explain exactly what the differences are in the results you get? Thanks! :D

15!!? Yikes! That's one third what I'm getting with This GS :http://www.dsmtuners.com/forums/hangout/428910-amazing-fuel-economy-my-420a.htmlAnd here, I dunno what year you have but they should be pretty much the same. The GS Spyder gets 20mpg in AT and 22 in MT. What I find interesting is...

the GSX is rated 20mpg combined GST is rated 24mpg combinedGS (N/A) is rated... drum roll23 mpg combined. go figureIt's just something to consider with gas prices climbing with no cap in sight. I'd say get the two, keep one stock for dd and mod the hell out of the AWD for weekend fun.

had a trip to Massachusetts today (average speed of about 67-68mph). Saw cheap gas and decided to fill up:It was a new gas station and the fill spot is flat (compared to the fill spot at my regular station). When the car is tilted down in the front relative to the back, I can get more fuel...

Yeah, I'm about to.... nvm, link is broken.

I drive 50mph, so I'm not worried :D . I did have my '96 sebring up to 136mph, and no problems.

As long as there are scammers, there will be the scammed. I dunno how these people fall for the obvious...well maybe I do. LOR (Lack of Research)

Why is it that whenever Chrysler has a good product...there are a ton of people who say it's because of another company, and whenever it's bad, they always relate it to Chrysler?...It really gets old.Anyway's, that and like half the posts above have not much to do with the OP's question...

^^ Interesting how the angles make it look like an Alero lol.

Thanks for bringing that up :)I wont recommend going above your max sidewall, but I'm being honest. I've run at max sidewall, but I personally find gains beyond this. The auto manufacturer's 32psi recommended pressure is for a compromise between a compliant ride and gas mileage.Just to add...

Those cars are rated right around 27/35 city highway and are fuel misers. A member had a car like that and regularly got around 55mpg. What did you do with it (modification, any changes etc.)

Awesome! If you you introduce yourself on the site, people will be more than happy to welcome you, ask about your commute and provide tips as well as expectations. Contrary to what is believed, the 4g63 turbo is rated pretty much the same as the 420a. AWD is what kills the mileage. Stay out of...

Well, I was told I only had 50 miles left..surprise surprise ;)

Update: Almost the end of week two on the same tank. Maybe I can get 175 miles out of this quarter? :)The community of which I'm a part CleanMPG don't actually make people feel bad about their cars or what they get. As long as you do your best to save gas within reason, they'll always be...

I have a gst exhaust on my 420a, so the above comments are right. whether or not it sounds better, I can't say. I did the entire exhaust at once.

I realize. I was just agreeing and adding to what you were saying.I don't "turn the car off", but I do have a motor-kill switch.

In fact. this has more to do with fuel economy than the engine, aero and rolling resistance combined. :D.It's nice to be able to match a prius in mpg and still beat almost any other N/A 4 cylinder in the 1/4.

I hypermile. I don't expect anyone here to be able to do this...without practice.

402 miles and slightly just above a half tank remains.Here's the weather pic for this morningAnyone think I can hit 800 miles on this tank? Any projections for the maximum I could get over one tank? Temps were mostly in the 30's for this tank. So you can be optimistic for...

Wouldn't do that to my car, but modify the headlights and tallights, hide all badges, and cover the engine bay with some high temp stickers. I know they say even bad publicity is good publicity, but...I don't think this sticker bombing thing is something the dsm community needed.

Thanks for the responses. My original thought was to go in and say that the law doesn't specifically state you cannot have a modified exhaust, it just can't be modified to be louder than stock. It's a noise suppressor. If i went to autozone to buy a pipe to replace any of my pipes, it would be a...
