Greedy

Hey guys, I'm new to posting but I've been reading alot of ur post, very helpful in my deciding what I want to do with my car. But down to buisness, heres whats on my car U/D pulleys,65mmTB,Flowmaster Force2's, basically stock. I plan on doing much more once I fully decide on an engine combo. Anyways I put my TB on yesterday and now its got good power through first but when it hits second it drops down to about 1000 RPM and its got no ***** at all. I've got no clue what it could be. Did I do something wrong? Thanks for any help you guys can give me. Oh yea its and Auto.

did you hook up the tv cable on the throttle body? its next to the throttle cable, i dont know if that would make it run bad or not, so you could check, is your tps set right? check thoes two ang go from their.

Sounds to me like you need some gears to keep the rpm up in the power range

How do set the TPS?

what do you mean has no *****?? you mean less than before or just not what you were expecting to gain from the swap???

Steed

never mind I found how to adjust it,and in reply to wild it has less than before but I think thats because of the tps now

the TPS wont change the performance enough to notice, mainly idle. you can set it to the lowest level and at wot it will still feel the same, but it will cause an erratic idle, lean off idle, and surging.

Yea I turned the idle lower yesterday it was at about 12000 now at about 7000 didnt seem to run any better or have any more power it does surge here and there you think thats from stickin?

i still dont understand the problem??? i think you just thought the TB change would give you some more umph, and it didnt, its merely a supporting mod in a way, essentially the stock induction system will work well until you change the H/C/I, and wont give you much performance by themselves. if it really is a very noticeable differance from before and after the TB swap then something is wrong. and to set the TPS you gotta have a digital voltmeter, after you set that you set the idle, recheck the TPS voltage, reset the idle, until both are right.
