Rebuilt engine, and also friend put on jumper cables backwards at night to jump.New ECU, cam sensor bolted to original position, and then removed to spin 180. Also hooked up 3in gm with maft sensor set up properly, No change Won't idle without help of throttle. Mechanic who installed new...

So since 2013 my 1990 laser has been dead. Now it has a new engine, but the mechanic most likely f***ed up on the vacuum line system. It idles horribly, and when given throttle stock boost gauge maxes out. Aftermarket stays at 0.

He said that top dead center piston has two different points. f***ing help. My understanding is that if the first piston is at the tdc and it's timing mark is correct, along with the cam gears. The first rotation is induction of air and fuel.

I k ow I shouldn't post here, but all my DSM friends have no clue what's wrong. She cranks beautifully(sounds better than she ever has) I'm quite certain there's fuel being sprayed into the block(checked with q-tip) and there's no spark. I bought a new coil pack and no difference. I was told...

I know there are things these cars are picky about and I'm not taking chances like I did with the hydraulic tensioner. Specifically my car is a 90 with the four wire. I'd test it, but all I find is how to test the f***ing three wire. Don't tell me how to do it. I do appriciate it, but I want...

I was told this isn't important. But I don't think that's right at all since it came with gaskets. Can some one please help me.

So I was told the burnt hole is fine and that the entire thing doesn't need any gaskets. Which I don't think that's right since there are gaskets for the timing cover. So I have no idea what to do at this point....

Searched gr4 mounting and nothing came up. So will a 1g motor and tranny mount into a gr4? Will there be modifications, just the trans, or even just the motor?

Um...car sat for months. Should be done soon, but where do I post the questions for getting it back up and running properly? I already have a plan, just questions.

I have two four bolt diff axles and they have 26 splines, the longer axle with the stubby splines has 21. Is this for a first generation?

All I found was 221

So after head gets looked at machine shop, I'm planning on installing a 3' gm, and I found this air filter. The top glue is kinda sloppy, but so far I have not seen any holes in the foam. Just kinda worried about the brand concidering there's no reviews. Got it in a auction for 13 when they...

I've done a lot of things, but taking off my first generation intake manifold was a nightmare. Any one else have some struggle stories or advice. I honestly can't see myself putting that horrible intake back on, just to take it off in the future.

no ecmlink Can someone tell me how to find out what kind of maf translator I have, and also I'm looking for the cover to the maf box.

I have the stock ecu. 90 laser.I bought a wide band and the turbo is out of the car. I am planning on keeping the original O2 and drill through the turbos O2 housing near the bottom where the down pipe connects. Reasons being are posts I've read state the wideband O2 doesn't last long at...

Posting here instead of the cylinder head and short block is because it says this. ->This forum was created for the more advanced DSM enthusiasts in mind, specifically, those who have already modded their DSMs past the Stage 2 point (400hp). Unless you have extensive experience in the building...

1990 Plymouth laser RS turbo. so I got my timing belt done a long time ago and not even 5 miles away the car starts jolting back and forth, I pulled over and killed the engine. rotated the cams and they looked lined up. car was fine after that oddly. though now it randomly drops 1000-1500...

So driving home. HP feels great and normal, but idle was odd at times and I noticed when I went to neutral with no gas pedal. Rpms stayed above 1000. It also felt like I lost 100 HP twice randomly, but only for a sec. Wish I had my logger. So I get home and go for a drive every thing...

Saw this at Walmart and since turbos require higher octane. Wouldn't this be good for my car. Or bad since it says racing only?

The cars timing wouldn't climb at all due to the knock. So I pulled over and cranked it by only turning the key to start for a half second till I got the marks as close as possible and it looked like it was done properly on the cams. But after doing that. No knock. Absolutely gone. Except...

So its 40 degrees tonight and on my 10 mile drive to work I noticed my temp gauge was on zero? Between the two lines on the cold side......if the gauge went from 0-10. It was more like 3. In the pic id say that's a 4.5 where the needle is.

So, STM has it for a higher price than extremepsi. Why is that? They both are the same kit.

One is when I took out the coolant sensor. After I put it in it seems to read low, but when I push on it the gauge reads back up to the center of temp. Do I need a new plug? Two is I let off my e-brake and let the car roll backwards in neutral(manual trans) and my rpms slowly went up at least...

No answers that involve get both. Only have the money for one or the other. So recently I contacted a tuner called my1gdsmtuner.com and I already have a ecu set up for my car at 320.50$ With it I can install a evo maf and get rid of the giant(in my opinion)piece of trash that's the 1g maf...

so ever since I bought the car. it looked like the alternator has been burning apart my serpentine belt. Noticed a lot of black prices in between pully and alt, but it never did anything when I drove it. Now my new belt burns and those shavings are back from where I cleaned the old ones...

So I have random knock showing up on mmcd. It seems random because its not under boost or wot. My1gdsmtuning said it was phantom knock? I was wondering if upgrading my old motor mounts would fix the problem?

I've noticed a slight difference between just quick turning the car off, and slowly turning it off. I know this seems ridiculous, but if its better to slowly turn it off. I'd like to know. If it was a 2000 it wouldn't matter, but I know how.....older cars have a life-like sense to them. If...

So I'm gonna buy a EPROM with it tuned for my evo maf for 320.00. And I was wondering if anyone has ever tried this. Since its EPROM. Couldn't I still buy the V3 cables and chip from ecm tuning and then fine tune what my1gdsmtuning did?

I'll do two second changes, and I'll start at idle and go for a bit. This log odly has very little knock. 25.000 RPM-1187 INJD-2.3% KNCK-0 TIMA-17° MAP-0.71 OILP/-1.56 OILT-66 27.000 RPM-1218 INJD-2.3% KNCK-0 TIMA-17° MAP-0.69 OILP/-1.56 OILT-66 29.000 RPM-1437 INJD-3.9% KNCK-0 TIMA-23° MAP-0.93...

So got back from a test drive and saw what looked like a valve. And I'm thinking. "Dah f***, is that. Looks like a valve".so I picked it up and woe and behold. Bolt

Belt running alt and water pump snapped and I pulled over when I saw the radiator, battery and oddly e-brake symbol lights. Now I'm stranded. Joy....

So I got everything working except couldn't transfer mmcd to my computer. Today I learned how to and imported 4 logs I believe it got stuck on the 5the one and I waited a whole hour to come back to it on the same log at 0%. So I canceled. After 10 mins of it trying to cancel I just pulled...

So my problem is I can't get my log off the palm and onto the computer. Everything works but that. Lol

So I can shift fine. Clutch....works. Yet no matter what gear I try. Only 1 and r. The car slightly moves then its like I slammed the clutch plate down and it moves in the opposite direction of the gear. I was able to force the car to move hoping the differential or something weird happened...

So...even with the wire adapter thing I'd need to tune the engine right?

So there are some days where my clutch pressure is fine, then others where is slightly low to where my throwout bearing rattles then goes away after a 5mile drive. Or after I hit 60. But I was wondering if its possible to get a slightly longer rod on the slave cylinder so that the clutch fork...

I just got off work and thought I'd sit in the car till 9 when my bank opens. And I'm listening to music with amp off. I installed a toggle for it.

I've been in my car for 10 mins and my battery has gone up while listening to music. Is that normal?And http://topgearstreet.com/90-91-Mitsubishi-Eclipse-4x6-Projector-Headlights-Black-8219.htmlI think I need to buy the double filament but no idea what the numbers mean. I'm guessing the...

Now my first problem is that my cabin fuse keeps blowing. Its a 10 fuse so I stuck a 15 in there since I don't have a ten, but wasn't sure how dangerous that is. Next is that I have a 1990 Plymouth laser rs turbo and I have a fuse for security, but the security relay is gone. No clue why...

Help. Where do these wires go. The yellow is going to the middle prong, and the green is going to the outside one. If your unsure which prong is which i marked them in the thumbnail.

I just bought the coolant sensor and it isn't even a direct plug in. Help.

Read the posts that pooped up from my title. Sorta same but mines different. My car took 20 times to start, I even trued flooring it when it sputtered on but couldnt get it going. I did get it to 4,000 but then rpms just dropped like I wasn't touching gas pedal. I did get it to start and...

1990 plymouth laser rs turbo My car ran fine. Cell came on yesterday day a couple times. Not its acting like its possed. I try to start it and the rpms jump up and down, it sounds not normal at all some other gauges are hopping around. I think its the ecu since the doors don't lock together...

1990 Plymouth laser rs turbo. 94% stock. Struts, wheels, exhaust manifold.So...it happened after I floored it when the light turned green. Not sure when exactly but I noticed it when I hit 65....1-3 miles after hitting 65 and it stayed on/off (stayed on for while, turned off. 1/2 sec then...

So ive been eyeing wideband kits and want one. But I really don't like the number ones. I like the ones that have. Rich/stoch/lean. And the light sweeps back and forth depending on air fuel ration. Is this design less effecient than the number ones?

Really I'm scared of doing it. I have a...well its a Mitsubishi round mass airflow sensor. Not sure if its a 2g or 3g. It has 7 pins and I really want to put it in with a maf translator, but scared or problems or repercussions. Will it give me bad gas mileage, will it idle bad. And if so can...
