Boucing idle only when brake is pressed
Posted: June 28th, 2009, 10:38 pm
I've read through a bajillion posts on what this could be.
things i've done to date is:
1) check for vacuum leaks, replaced with a CAI, sprayed lines with TB cleaner, checks out fine
2) added grounding wires daisychained (was told toa dd one to alternator but haven't done this yet)
3)replaced TB, IACV and distributor with working ones pulled off of a friends car (that didnt have idle problem)
4)adjusted TPS, the idle cable thing
5)adjusted idle with 10 and ground
6) tested battery, starter and alternator
the thing that really bugs me is that it only happens when brake is pressed, could it possibly be a dying alternator? it was tested at canadian tire and everything checked out, but i think i read somewhere in here that it could still be a problem
it does seem to be some sort of electrical issue, and the bounce only happens a once to a couple times, but every time i stop.
does anyone have any more ideas? lol
edit: i should mention that i DIDN"T have this problem yest after i did 3) but today it was raining really hard and when i went to drive, i noticed the idle problem was back....(i had like <24 hours of happiness as i thought the car was fixed but it could have just been fluke yest that it didnt bounce)
