    94 c1500 ignition acting funky

    PCM 92 yukon

    Ok guys and gals. The tinkerer is back. So I had an issue with my 92 Yukon 5.7, it was idling high and then it was shifting funny. Missing shift points/rpm as far as I could tell. Well I took it to a shop just to have diagnosed because I was thinkn vacuum leak somewhere and...

    High idle, goes higher when brake is pushed

    No I haven’t. But no fault lights are on the dash so never even thought about that. I also thought about changing tps, but would the brake being pushed have any type of affect on the tps? Again I’m a tinkerer not a mechanic

    High idle, goes higher when brake is pushed

    Pulls to the floor. But it doesn’t seem to idle as high for and not as long when I do that and start it. But I did pull the vacuum line off the booster and try to plug it with my thumb and that didn’t seem to change much.

    Took off air cleaner and looked. Same thing happened in my 94 c1500 I haven’t touched the booster yet. Gna swap this first pulls to the floor.

    High idle, goes higher when brake is pushed

    Well That makes sense. So I Just purchased and just goin through it tryn to fix any issues. I know my BIL supposedly went through the brakes so it’s very plausible he missed that. I’m just tryn to work out all the little bugs. 92 Yukon great condition. The soft brakes have been like...

    High idle, goes higher when brake is pushed

    Thanks bud. That will be the first thing I try when I get home. Idk if this helps but before all this started my brake pedal was super soft, so I was gna have the brakes checked anyway. I know if a booster starts to go bad the pedal gets harder. Is there any...

    High idle, goes higher when brake is pushed

    Ok guys and gals…. Need a little bit of direction. 92 Yukon 5.7 Pretty sure it’s a vacuum issue. High idle when starts about 1300 rpms. When I press the brake pedal and let go of it the idle shoot’s up even more about 3-500 rpms. Did a little research and found that a...
