Hey guys, maybe you can help? When I start to excelerate the car seems to hesistate then go. What do you think? A bad TPS?

Is the car still cold when you try, ori s the car warmed? Try to add some more info, that way we an narrow it down a little for you. How old are your plugs & wires? Does the car idle normally? Any difference in gas milage lately? Just some thoughts.

This happens all the time, when the car is cold and warmed. The car seems to idle fine, the plugs and wires are new. As for the gas milage I couldn't see much of a difference, because I have done some mods to it. Also the engine was just rebuilt.
Thanks, Steve.

Steve,

Are you throwing any codes? Perhaps you've got a bad sensor somewhere. Mine was acting like that when I had a bad O2 sensor (only when cold), so I'm not so sure it's the TPS.

Have you checked for vacuum leaks?

Cheers,

Sean

Sean thanks for the reply. No I have not checked for any vacuum leaks. I think I will try that next. Thanks.
Steve.
