I just installed Mac equal length headers,Mac Pro Chamber,2 chamber Flowmasters with turndowns.Great performance and sound,but it acts like its running rich at idle. Anyone had this problem?I also removed the A/C and smog pump.I would like to know the length of the belt to run.

Whats it doing at Idle? Have you ever adjusted the TPS? That's throttle position sensor. That the two wires comming from the throttle body. You need a digital volt meter to do it.

What did you do with the O2 sensors? On long tubes they are further downstream and that can effect how the engine runs.

Yes, I did adjust the TPS to .098,engine off. Engine running, I get about .100-.101.The 02 sensors are new and in original location. At idle,seems to be running rich.If I slowly raise rpm's, it sputters, then clears up.There is no problem driving when the rpm's are up. I also have a cold air induction kit,(fenderwell) with stock MAM and T.B. I'm thinking possibly not enough air flow at idle.
Thanks for your reply Jimb. Andy
