I have a 99 Tahoe that I purchased in May. Right from the start it had an issue with intermittent bucking, mostly under the following conditions - after upshift from 3 to 4 especially under load, at highway speeds when letting off the throttle and then trying to resume acceleration, and sporadically while driving at steady speeds.
I've had several mechanics look at the vehicle, I have replaced the fuel filter, distributor(with an all metal NEW distributor, not a reman.) and had the transmission completely rebuilt. The symptom still persists. The truck is drivable, but the issue is making me insane. It's been suggested that there could be slack in the timing chain, possibly an issue with an injector, maybe an electrical issue with the ignition, but nothing shows on the computer.
The engine was replaced before I bought the truck, and it runs perfectly with the exception of the bucking issue. Idle is perfect, acceleration good, everything seems right.
The vehicle does have a remote starter, and I have wondered if that could be related to the problem.
Any help would be appreciated.
