The title pretty much says it all. I have an 84 e with about 250k and a slush box with about 90-100k on it. Picked the car up in october for 700 and have been troubleshooting ever since. Since I bought the car, the following things have been replaced with new or better condition parts:
- air filter
- oil and fillter
- oil pan and gasket
- 02 sensor
- injectors
- fuel rail
- fpr
- vacuum hose from valve cover to tb
- 2 icv's, cleaned both thoroughly
- adjusted afm to run on fresh track
- wr8lcs plugs from an IX (cleaned up, read they are better than anything)
- shocks and springs
- tires and basketweaves
- belts
- battery
- plugs wires
- cap and rotor
- vacuum hose from fpr to manifold
- cold start valve
- bushings for alternator
The problems I'm having is that the car runs rich, almost to the point of getting too much gas. When the car is cold, it runs fine, barely stumbles at all, but now that it's getting warmer here in central Texas, the symptom has gotten a lot worse. So much worse that it's died on me at lest 5 times in the last week. Most of my driving is done at 65 to and from work, but on the way back it's in stop and go traffic. The car wants to die as soon as I let off the brake and step on the gas. Sometimes I can get away with easing into the gas very slowly, other times it's no bueno and the car stalls in rush hour traffic. It sputters and sounds like it's dropped a cylinder/missing and pours black smoke out the back. Not quite modded diesel quantity, but enough that I can see it in my mirror. When it's warm, sometimes the car hangs out around 500-600 rpm and has a hard time keeping an idle. I've checked everything I can find and still can't find a reason as to why it's stumbling. I searched for over a month on here and e30tech and still can't figure it out.
While searching, I've tried several test to narrow down my problem and I've noticed several things:
- when I remove the oil cap, idle doesn't change
- I used a mustang o2 sensor, and had to pull it today to rewire and the tip was already black. I put in the new one less than a week ago.
- while in park, if I rev the enigne and it stumbles, black soot and what I assume is gas come out the exhaust.
- I checked the intake boot for cracks, found none
- used carb cleaner to check for vacuum leaks, can find any
- pulling oil dipstick does nothing
- air filter is clean
- seafoamed when I got it, 1/2 can through motor, 1/4 in gas tank, 1/4 in oil
- cleaned connections on all coolant sensors, afm, tps (clicks just after opening TB)
- properly gapped cps to .040"
I'm all out of ideas and any help would be greatly appreciated. It's getting annoying having to deal with a car that stalls out almost every day on the day home, as I love my e30 and really don't want to sell it. I'm sure I'm forgetting something I've checked or done and again, I have done extensive searching. Even started reading the bentley cover to cover.
