idle issues...

pgtxtc · 10-28-2010, 06:02 PM

yes i have done research and hjave tested a few things...no help, it started the other day after it warms up ill come to a stop and th eidle will go to about 1900rpms..... now if i have my foot on the break it will drop idle to about 1100 and rise and drop and rise and drop, if i dont have my foot on the break it will stay about 1900 and start getting hot

any ideas???

sounds like a vacuum leak at the brake booster, try replacing the vacuum lines

^This. Check all the vacuum lines that you can. Mine was idling at 1100rpm and would go higher if I turned my "a/c" switch on. Turns out that one of the lines that goes to the charcoal canister was off. She idles perfectly now.

Total brake booster vacuum leak. Is usually just a worn vacuum line.
