Ok so my FD started with the whole "bouncing idle" today but its not idle hunting as if i had a vac leak because if i run it up in the rpm range it will continue to "bounce" about 500 rpm regardless of where the throttle is run up to. I read out the TPS and im within the correct range so its not that and i misted with starting fluid to check for the vac leaks but there were none.

So does anyone have any ideas ????

 

what upgrades do you have??



may be the wax pellet.

may be Idle Speed Control

 

id check compression...

 

are you running PFC?
