My 1997 3.1 Chevy Lumina LS is having a bucking feeling upon acceleration from a stop sign or stop light. It only seems to do it once the car warms up though. I used to live in Tucson, AZ, which is where the problem started. Since I have moved back home, I haven't had the problem. Then again, this is a small town, and it doesn't take me long to get anywhere. Went out of town a few weeks ago, and had the problem though. Have replaced the TPS, fuel filter, air filter, spark plugs, spark plug wires, oil and oil filter. I saw in a previous post that someone drained thier tranny fluid and replaced and added Lucas, so was going to try that. Dealer said it was the main computer, but I don't really have problems with anything else.
When I went and got my emissions test done, it came back with a 0300 code I believe, which was misfire on cyl #3. I'll have to check. I think I wrote it in the book.
Any help would be appreciated.
Thanks.
