  1. Need help interpreting OBDI codes for my 92 Lesabre

    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...
  2. 92 Lesabre has no acceleration after 60+ miles of driving.

    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...
  3. 92 Lesabre boiling coolant in the overflow reservoir

    I've got a problem with my 92 Lesabre, where it hesitates at full throttle and sometimes gives a check engine light. I popped the hood to look at it after a good long drive, and heard the curious sound of boiling water inside the overflow bottle. The coolant must be hotter than hell to make it...
  4. Putting an older (no airbag) steering wheel on a 92 Lesabre

    I've got a 92 Lesabre with the horrible first generation airbag and weird horn buttons. I've put up with it for years, but today the airbag warning light started going off. I take it this means the airbag won't be inflating, not that I ever put much stock in something so ancient to work...
  5. 92 Lesabre poor acceleration, ICM/Coil issue

    My Lesabre has had an issue for a while now, where after it heats up, it runs like crap. Terrible acceleration, it struggled to get above 40 mph. After testing the MAF. air intake and cat converter, I'm pretty settled on the issue being in the ICM or coil pack. But there's an issue that has me...
  6. 92 Lesabre no acceleration when hot

    I just got done limping my Lesabre home through heavy traffic. It couldn't go faster than about 50 mph. Over the last week or so I had noticed a drop in power once the car heats up, and today the problem seems to have come to a head. I spend a LOT of time in traffic. Today's trip was about 30...
  7. 92 Lesabre hard idle on startup and trouble shifting

    I have a 92 Lesabre with about 58k miles on it. Usually it's a good car, but today it idled very hard when I started it up. When I put the car in gear, it would not shift out of first. However after a minute or so of driving, the idle returned to normal and the shifting started working again. If...
  8. 92 Lesabre stuck in park

    My 92 Lesabre Custom has an issue where twice now, I've tried to put the car in gear and found the shifter wouldn't move from park. Both times it happened when the car had been running a while. I parked momentarily and found that I couldn't get the car back in gear. In both situations, I turned...
  9. 92 Lesabre water pump replacement woes

    Hi there. I've got a 92 Lesabre that I've owned for some years now. It's been a decently easy to work on car until I ran afoul of this particular issue. My water pump recently went out. Easy swap, or so I thought, but it turns out my generation of Lesabre requires you to remove a motor mount to...
  10. 92 Lesabre multiple bad TPS

    Hi. I've got a 92 Lesabre that I'm pretty much at my wit's end with. This thing has failed three different throttle position sensors. At this point I've tried two off-brand and one actual Delco model. Clearly there's some kind of fault in the wiring. Or, alternatively, the wiring is fine and the...
  11. 92 Lesabre Braking Problems

    Hi, this is only my second post in this forum, but I could really use some help with my car's brakes. It's a 92 Lesabre with about 45k original miles on it. Recently the car developed some really bad wheel shake while braking. So far I've replaced the front brake pads, calipers and hoses, as...
  12. 92 Lesabre Mass Airflow Problem

    Hello. This is my first post at this forum. I looked around but couldn't find anything relevant searching. I have a 1992 Lesabre. It was my Grandma's car when she was alive. I've had it for a few years now, running it fairly trouble free. It has less than 50k original miles on it. Practically...
