I have a 2000 trans am m6 with borla exhaust. Only had the car for about 2 months. The problem is the engine does not sound smooth at 3/4 or wide open throttle(bring the rpms up quick). I can slowly bring the car up in rpms and it sounds great and very smooth. There is no computers codes. It sounds to me like the car is a little out of tune. Just replaced the plug wires, new ls1 lid, cleaned the throttle body, and had the dealer clean the injectors. Also when the battery was unhooked for a long time the car did the relearn at idle. The car seemed to run better for a few miles and then started to go back to running rough. I had two 99 corvettes this is what I am comparing the trans am to for engine performance. Yes I do know the trans am has less power but it just is not as smooth sounding as was the vetts.
Help

I replaced the plugs, wires, and a new air lid to try to get the car to run better. I guess I am not happy with the car.
As for trans am and corvettes having the same power, The f body cars have a smaller cam and from owning a vette a vette is a lot quiker then a fbody in every day street driving. Quarter mile times are about the same(from what I have readed in posts)
Thanks for all the info!

WOT params are not learned (except for spark table
in the face of excess knock). However closed-loop
learning in the presence of problems can affect WOT.
Specifically a natural-lean (like from an unnatural
MAF miscalibration or such) requiring positive trimming
puts positive fuel adders onto WOT as well.

I'd try a new fuel filter. Won't cost you much and
definitly can't hurt, just a maintenence item.
MAF maybe? Have you messed with it.
Do the RPMs rise smoothly? Think its the clutch?
