No luck, last thing i tried was to unbolt the downpipe to check if maybe the cat was clogged but no change. I live in the N.E. area off naco and o'connor.

I changed the power transistor. It still drops idle and acts like it wants to die. The plugs look ok, and good spark from the wires.I noticed a lot of liquid at the muffler, now I'm not sure or not if it was gas.

I changed out the power transistor and it smoothed out somewhat but still drops rmp and acts like it wants to die and looks like raw gas from the muffler.

i did check for that, compression is 175-180, i just changed the power transistor and got a change, now it dips idle and its running so rich that i;m getting unburnt gas at the muffler.

How do you read pulse width? The only thing we used other than a multimeter was a noid light

does anyone know what the voltage at the injectors is supposed to be? my brother -in-law was a master tech for many years and he tested the injector wiring and it was reading full voltage (13+) volts, he said it was only supposed to read 5 volts.

the ignition control module is located just to the left of the coils packs, it has a rather wide connector plugged into it.

i bought a brand new coil pack, plugs and wires, and its still doing it, i even replaced the fpr, had a fuel pressure test done and nothing.

where is the resistor pack located?

What, if any are the differences between a head off a 96 4g63t and a 98?

I have a 98 gst, about a week ago it threw the random misfire code, bucked, sputtered, backfired and quit. I had it towed home, changed the spark plugs (checked gaps) plug wires, coil pack, fuel filter. after theat it seemed ok till it got to operating temp the thre another code for misfire...

But the last code it threw was for cylinder 3 misfireok, its not the timing, funny thing is that the stutter isnt constant, it does it once or twice every couple of minutes, but gets worse after its been driver 10+ miles. after about 14 miles the ilde started to bounce around about 300rpms or...

Ok, replaced injectors, everything seemed fine till I drove it to work. It's stuttering a lot less, but I am getting either misfire or detonation. What else could this be?

ok, tps and maf are fine. it was running rich, so as suggested I drove it for a about 3 miles and it threw a cel, cylnder 3 misfire. before it was random misfire, so i'm assuming the injectors are going bad, I had my borther in-law come over and check the injector pulse with a noid meter and...

i had the battery out for a couple of days, i'll test the maf monday, i'll be working for the rest of the weekend, thanks guys.

the isc is the only thing i haven't checked, yes the plugs are properly gapped. and btw its not going up rpms at idle, its going down.

I checke for vacuum leaks, it threw the random misfire code before i replaced the aforementioned parts, no cel now though.

I'm just getting back into the dsm scene, I had a 90'GSt before, noe I have a 98GST, last sunday it started to run rough, the rpms bounced all over the place, then it backfired a few times and died. I had to have it towed home, so far ive replaced the plugs, plug wires, coilpack (it was bad) and...

pick and pull has been picked clean, and roosevelt u-pull it only has 2g 420a eclipses, good for misc parts. I picked up two good rear hatch struts last week for five and change each. I found a possible on CL, i'm gonna try to meet the guy for a look tomorrow morning. its a TD05H, not sure if...

I'm looking local for a 14B or 16G turbo.

close thread, i bought this.

I read somewhere on here that the idle control valve was part of the throttle position sensor, i'm not sure if that is accurate, but if it is you might be stuck replacing the tps.

I didn't like what he said about "valve problems" you might need to do a cylinder compression test to check for bent or stuck valves as well.

did he say anything about spare parts including a spare head, if so i almost bought that car.

I don't know if this guy still has this gsx it needede a battery and front motor mount out of penitas tx, I had him talked down to 3k but the wife said no to the color, anyway here's the link: 1998 Mitsubishi eclipse gsx

did you buy it from a guy in austin?

poss boost leak, check your injectors, fuel filters, tps sensor, coil pack, and check for shaft play on the turbo. Also check the intercooler and piping for oil. then let us know.

I could probably be more help, but I'd have to see your car and listen to it run. I'm usually available mon- thur during the day. I work fri- sun. my number is 268-7731

I'm bored and my wife's working a 7p-7a shift tonight, anything going on tonight 6/21/12?

you can close this thread I GOT ONE!

My car was totaled about two weeks ago and i'm looking for a 95-97 ish eclipse turbo 5speed looking to stay around 3k ish, already looking at two cars but it will be a bit of a drive for either, craigslist has thin pickings right now or unrealistic prices. I'd like to find one local.

try pick-n-pull on applewhite rd or roosevelt u pull it on roosevelt rd just outside 410.

I had this crazy idea last night and wondered if anyone has tried this or if it would even work. Take a 2G mas and use silicone reducer/adapters to change its placement from stock position to place it instead inline into the upper intercooler pipe after the bov. This would give those who want a...

no grinding, it just feels like i'm in neutral. even in regualr driving it feels different that it used to when I shift into second. feels loose or soft, don't know exactly the word to descrobe it properly.

I have a 90' GST mostly stock except for a voodoo racing mbc and datalogger. I took it to the local track, after my first run, I can't seem to get second gear to engage above 3k rpms or above 25mph. If I drive regular without goosing it it will engage, but it still feels weird when shifting from...

attach some pics of your setup.

I did a search but found nothing that helps. Here is my problem: Sometimes my aftermarket guage will not register vacuum, the one in the cluster does, but not as much as it should while cruising, if I give the car a modest amount of gas it spools up the turbo. As I said, it only does this...

I got a price of $320 here in San Antonio from Lone Star Mitsubishi, Your local dealership is overpricing it.

So the pop up motor and the lights are both powered by the same relay? That would explain alot. the pop up motors work but not the lights themselves, I guess its only partially burned out. Now to find a replacement, thanks for the info.

My headlights are out, i checked all the fuses and the fusable links on the passenger side under the hood. I went to the parts store and they tried to sell me a headlight relay switch, the chick behind the counter told me this relay was located under the driverside dash. I spent a day or so...

I bought a set of white gauge faces from ebay, (never again) I had to pull the needles off to fit them on. Now they don't seem to read right anymore, is there a way to recalibrate the cluster? I made sure that the needles could move without restriction, but the temp gauge sits alll the way down...

i couldn't find windo weld, I am using liquid nails polyurethane.

The problem with that Silver is that I also need quite a lot of stuff done to this car, so I'm going the cheap route wherever I can.Can someone post the link to the windo weld method? I can't find it anywhere.

I can't seem to find the name of this part anywhere, and the dealer is closed today. Here is the Pic. It came off the throttlebody of a 90' turbo Eclipse.

Do you have Advance Auto Parts up there? If you do I'd suggest buying a lifetime warrantied on from them, mine has been going strong for 2 years now with no replacements. Also check your alternator relay.

I looked on vfaqs, and did a search here but didn't find an answer, so here goes: I have already used liquid nails polyurethane to fill my top driverside mount, it worked great, but it took almost a week to fully harden I no longer have that kind of time to keep the car down. My question is...

Have you checked your 02 sensor lately? that was the cause of mine a bout a year ago.
