Bucking at part throttle

Could be the cam duration if you are running a 5-speed or you could be runing rich or you could have the tps set to high for the idle speed that you are runing. See if you set your idle speed low and your tps high you are going to have problems.For example when i installed the cam in my gt i had an idle speed of 800 rpm and the tps was set at 0.97 and when i drove it the it was bucking at cruise. But when i lower the tps to 0.82 and adjusted the idle to 900 rpm it was fine.You don't really need to turn the tps up high to get good throttle response because the computer will adjust and you will have good throttle response at 0.82 and less bucking.Try it good luck.

Possibly, or you have a wiring problem, or problem with the computer. Try just testing the black wire of the TPS to a ground. See what the voltage reads. May also want to try and run the Key on, engine off codes also.

Set your tps from .080 -0.90 and set the idle to 900rpm because you're running the F-cam and you will be good to go
