Hi there
my car seams to have a rev bounce at idle between 1600 and 1800 i took it to my mechanic and they looked all over it and came to the conclusion that the tps was not the right one for my throttle body??

i have a aftermarket 70mm throttle body, do the stock tps work on these or will i need a new one?? or is this not the problem

btw done full boost leak test and everything is fine there

 

i dont see why a TPS would be causing you to idle so high. You probably need to readjust your BISS Screw to get it idling where it should be.

 

its weird i put my foot down a tiny bit and it starts to bounce makes taking off annoying thats why they thought it was the tps

 

is your car tuned?

 

not yet looking at doing in within the next 2 weeks think it will stop the problem?

 

There is a good chance a tune will fix the problem. What mods does the car have or atleast what has been changed since the last tune? Any issues I have ever had with idle is a MAF problem or a tune problem.

 

Yah im pretty sure you just need a tune. you are probably hitting a load cell that has some funny timing in it or something that you normally wouldn't be. Im also thinking that 70mm throttle body cant be your only mod, so definitely go get a tune.

 

ive changed all the intake and exhaust to 3 inch and new plemum,custom made 50mm extrators and so on

yea always thought it needed at tune but just checking it wasnt the tps
