I spliced on the junkyard pigtail and cleared the codes. Drove it around and the CEL came on once for a brief time. Got home and pulled a code 22. So, still TPS issues, but not as bad as before. My next steps will be to change the TPS, get a good OEM pigtail, and if that fails. I'll run new...

I put a new pigtail on, but this only caused the CEL to turn on constantly. Defective I guess. Cheap Autozone crap. I spliced in a connector I found on a Delta 88 at the junk yard. It doesn't look much better than the one I had to start but at least the light went away. I'm letting the car sit...

The plugs and wires are fairly new, but changing them is one of the next things on my list of stuff to try. The ICM is brand new, and a genuine Delco product. I've changed the ICM a few times in chasing this bug, and at this point I think I can rule it out. I do have a few extra ones I can swap...

Thanks. Going down the list, it seems I must have a fault in the wiring between the ECM and the TPS. That's the prognosis for both code 21 and 22. For 31, it says my Park Neutral Position switch has a fault. I wonder if this might relate to a condition the car had last year, where it would get...

I recently posted about how my 92 Lesabre was having trouble running right after extended driving. After 60+ miles it seems to have no acceleration, and the problem gets progressively worse until the car barely drives at all. Then once it cools down overnight, it's fine again. After replacing an...

With the sensor on, the car runs pretty much like it's been running for the better part of two years. Sluggish and poor gas mileage. I assume if I drove it far enough it would have the acceleration issue as well. With the sensor off, I get more power and better mileage, though the service engine...

The parts company sent the wrong O2 sensor, so I'm still waiting on the new one, but I'm confident to have found the issue. Now my biggest problem is that the lousy shop I took this car to all those years ago that changed the sensor apparently cross-threaded the thing and torqued it down with an...

I seem to remember having this O2 sensor replaced at one point. It's not OEM. I had to have like $900 bucks worth of work done to the car for it to pass its very last emission test, and the sensor was one of the things they changed. Thing is, the light hardly ever comes on with the sensor...

No, my scanner doesn't work on this car.

Okay, think I might have this problem sewed up. I drove the car long enough to get it in the trouble state, then examined the cat. No redness that I could see. I located the O2 sensor but didn't have a big enough wrench to get it off. I think it's like a 23mm? I also couldn't find the fuse for...

At this point I'm committed to chopping this thing. The car will never be emission tested again, so a cat is just dead weight. This way at least I can recycle it and recoup part of the cost from paying a shop to weld it for me. I can get a fouler cap to cover the O2 sensor so the check engine...

Yes, the plug wires are new as well. Not very often. It happened today because I'm still unsure if it's getting totaled or not, so I've been hesitant to fill up. It's actually pretty hard to tell how much this car has in it when it gets below a half tank. Now I'm thinking I might put one last...

I've got a problem with my 92 Lesabre that I just can't pin down. The car drives great, perfectly, for about 60 miles. Then it starts to have no acceleration. Step on the pedal and nothing happens. The only way to get it to accelerate is to feather the gas pedal, but even then the problem gets...

Ok, after driving it around with the new thermostat I can see it still has the problem. Not quite as bad, but it's still there. The check engine light didn't come on, but it started hesitating after about 20 minutes of driving. That pipe on the top of the rad is still hotter than hell. I can see...

After taking a drive, I felt that hose, and it was hotter than hell. I'll be putting a thermostat in next.
