Installed the new TB

[02 Mineral Gray]

I installed the Accu-Fab plenum and 75mm TB, The kit came from RPM outlet and it included a 85mm MAF housing. They told me to reuse the stock sensor in their housing.
My problem is the car is not idiling very rough. Could my TPS need adjusting?

What should the voltage be on the TPS at WOT?

Any help would be great.

Not idling rough? Do you mean it is idling rough? Not trying to be an ass just thinking you may have typoed.

I know that if the stock sensor was not installed in the housing properly it can cause surging and poor idle.. You may want to take it back out and ensure it's seated / sealed properly.

Just a guess..

Thanks.. Thats what I meant it is idiling rough, I will try to remount the TPS and the MAF.

If its idling rough, you may have damaged your IAC (idle air control) makes sense dont it , or you could have a vaccum leak somewhere. Double check ALL your hoses and connections to ensure you didnt miss anything. Id bet its a vaccum leak somewhere, but if thats not the case its more than likely your IAC which is around a $60 part. Do you have a "hanging" or "stuck" idle, or is it just jumping everywhere?

It hangs at 1200 then drops to normal. I checked the TPS and voltage and it is ok.

um..did u reset the Computer??

You can try resetting it after you get your odd idle figured out, or you can let it relearn on its own. Mine hung at around 1500 for the first couple days, then dropped to 1200 or so, then to 1000, then to normal where its stayed.

Thats another reason why I dont want a TB cuz everyone has problems with hanging RPMs...just the plenum didnt jack with anything on my car.

Same here...give it a week, it'll settle down.
Put the OEM MAF back on though...absolutely nothing wrong with it and most aftermarket tubes simply lean the motor out (inconsistently, unreliably) to make any more power...not a safe, wise thing to do.
The TB and aftermarket plenum allow the motor to pull like a motha above 3K...that's where I noticed the increase...below that, not much, if any.
