got a bad problem w/ idle

[badmanferg]

.....when im @ a light and im on the brakes the idle drops from 850 to abt 3-400 rpms and the idle will bounce in btw those numbers until im off the brakes...first i thought my stereo was putting too much of a load on the car but the problems there whether or not i have the stereo on, lights any thing electrical....any thoughts...

i had a similar problem and I cleaned my throttle body to find it was a mess and that solved my idle problem. You could also try cleaning your Idle air control valve.

maybe a vacuum leak somewhere

hmmm kind of sounds like my problem, but my car will just die when i hit the brakes...............

still working on this prob, all vacc lines are cool except the one for the MAP...that line seems a little shady so i'll check that hopefully by tomorrow, in addition though i notice that if i use the power windows the idle drops the exact same way as w/ the brakes.....

hmm my idle doesnt drop if i use the power windows.....
but today i took my intake manifold and intake plenum off, i've started to completely clean both of them out, ive got A LOT of carbon build up. im thinking maybe all the carbon crap is causing my air flow to not be so good. ill get back with my results

I recently had a idling problem but mine would idle very high with my foot off the clutch but as soon as i push the clutch in it would quiet, my problem was the choke pull off, it was getting stuck.

Try cleaning out the IAC valve.

co-worker says brake booster because that takes the most vacuum from the engine.

[i_love_cb7]

I putted in some injector cleaners and no more shaking at low idle......
