ok ,got one for ya. when the 3.slo engine is warm and you apply the break the idle jumps between 1 and 2 grand any ideas? i already replaced the TPS and the problem is still there.... battery is good and alternator is great so why the issue?

 

it has to do with the power brakes, that hose that runs off the the intake to the brake booster " vacume powered " I pretty sure everything with this setup will do that if you pump them. Very weird!

 

idle control valve give that a lookin at....had the same problem and tryed the brake booster but wasnt the problem...so just check the booster if not that then idle control valve most likely your problem.. good luck with it

 

tryin backing the idle down

 

I BACKED THE IDLE DOWN AND STILL THERE JUST LOWER RPM'S

IDLE CONTROAL VALVE IS A NO TO BUT THANKS

BRAKE BOOSTER IS FINE I HADDENT CHECKED THAT BUT I HAVE NOW, THANKS, BUT THE PROBLEM PERCISTS

ANY OTHER IDEAS?

 

Hitting the caps lock button? Perhaps check the vac. line to the brake booster for leaks.
