Hey guys, on vacation with wife in HH, SC in my Roadmaster Wagon. I had a check engine light and car started running bad. I pulled over, checked codes with my OTC 4000 scanner…it had multiple codes whereas it previously had none. All indications are pointing towards a bad ecm or maybe a bad...

Hello all, First, I'd like to say that I maintain my 2012 Buick LaCrosse Leather Trim Package 3.6L VVT vehicle with an oil change every 3,000 miles. Full synthetic & new oil filter. Secondly, whenever I have to do a repair on my vehicle, I use GM OEM parts. AC Delco. Nothing cheaply made. I...

Tryna sell parts from my regal but I ain’t getting far. I’m using the engine exhaust rad intercooler . Everything else is up for grabs including the tranny and computers. I got good body panels from the doors back.

I have a 1994 Buick Regal Custom with the 3.1 L V6 (L82), automatic. About 2 weeks ago while driving, the car just stalled/shut off. I got it started again and drove it a few more miles, where it died for good. I took it to the local mechanic who said that it needs a new computer, and that...

My ECM went out in my Park Avenue. I am getting conflicting stories about putting in a replacement. I am being told that the new one does have to be reprogrammed by some people and some are saying not. I understand the 1995 and some early 1996 are plug and play (basically). 1996 is the first...

Hi all, I've got a 2005 LeSabre Custom that has a really tricky problem that dealerships haven't been able to answer for me. Twice now, the car has not been able to start. Turn the key and nothing happens - at all. Windows, locks, trunk release, instrument cluster, and dome lights not working -...

Here is the issue on my well maintained 1995 Base Roadmaster with 102K, It all started last December when the car wouldn't start. I knew she needed a few more parts changed and this was the opportunity I needed to get her ready for a summer of camper pulling road trips. So I replaced the...

It appears to be a common problem with the Clusters on the 2000-2004 centuries that the LED display capacitor goes out on the clusters. However, most of the posts I see involve people fixing the display Mine did this about 6 months ago and I had been driving around with no odometer, keeping gas...

I have a 1996 Park Avenue that started having certain very common problems. Kept wanting to die without warning, then not wanting to start back up until it had "rested" for a while. Power; Windows/Locks/Seats would stop working, especially when it was wet Charging issues. Sometimes, the...

2000 Buick Lesabre won't start. When I crank the key over it sounds like it's gonna start but won't catch, like it's almost there but not quite. First I thought it was the cold weather (7 degrees here for a few days) turned out I needed a new battery, but still wouldn't start after replacing...

So... I spoke with a close friend which is also a Service Director of one of the largest GM dealerships in TX. I asked about tuning and a re-flash of the ECM, he direct comment was don't do it under warranty "no matter what!" He said that if you have any problems with the engine,tranny, turbo or...

Misfire on #3 cyl. 123,000 miles, regular maintenance, AC Delco parts. I have three 3.8's in the family, so I stock parts in the shop. I replaced the Magnavox ign module, Delco ign wires, plugs, coil pack & fuel filter mostly because of age & mileage. I did have one ignition module go out...

I have a 1991 Buick Century Custom (3.3L V6 MPI OHV 12V). I recently acquired this vehicle and it has been quite the nightmare. About a week into having it, it started overheating without warning. I have since fixed that problem by replacing the radiator and that seems to have done the trick...
