unccpathfinder Posted September 24, 2009 Share Posted September 24, 2009 So I have no codes or CEL light on but when I come off the highway my truck sometimes will die when i hit the clutch...usually in town if I come to a stop it wont kill out and will just drop to idle like it should but I've had it happen several times when I come off a highway or hit the clutch while doing 55+ the RPMS just drop straight to 0, truck dies and I either hit the push start or drop the clutch so I can have my power steering back I was thinking at 1st that the throttle body may be springing "closed" when i let go of the gas or possibly a vacuum problem. This sucks b/c I'm fixin to try and get it registered in CA finally and it doesnt give me a good feeling knowing it acts up and what may happen during smog...that and when i take it to DMV with no bumper, broken front glass, tires sticking out of the fenders and a federal MPFI in a cali TBI truck engine is 95 3.0 MPFI Link to comment Share on other sites More sharing options...
adamzan Posted September 24, 2009 Share Posted September 24, 2009 Sounds like when my MAF sensor wires were messed up. Try wiggling the connector, that worked for me for a while. Link to comment Share on other sites More sharing options...

GrimGreg Posted September 24, 2009 Share Posted September 24, 2009 If you said when you hit the brake, I would have guessed a vac problem, but the clutch doesn't have a booster on it, nor any other vac line to the system. Link to comment Share on other sites More sharing options...
sammyb33 Posted September 24, 2009 Share Posted September 24, 2009 IACV check and clean it... Link to comment Share on other sites More sharing options...
unccpathfinder Posted September 24, 2009 Author Share Posted September 24, 2009 I was thinking IACV actually...esp b/c it idles rough sometimes.... If you said when you hit the brake, I would have guessed a vac problem, but the clutch doesn't have a booster on it, nor any other vac line to the system. Yea that was my thought too and if it was a vac leak i would probably hear it and it would be a constant problem... Link to comment Share on other sites More sharing options...
sammyb33 Posted September 25, 2009 Share Posted September 25, 2009 Yep. Sudden stalls from otherwise normal "back to idle" situations, first place to look, IACV. And especially since you have an idle problem as well...... Link to comment Share on other sites More sharing options...
rydsno Posted September 25, 2009 Share Posted September 25, 2009 Same thing happened to me the other day, but mines an auto. It would just die if i let off the accelerator. Managed to limp into a parking lot, popped the hood, wigged the MAF sensor plug. Started right away. Went home and secured it with a little electrical tape, and it's never happened since. Don't know if it was the same as what you have, but sure sounds like it. Link to comment Share on other sites More sharing options...
westslope Posted September 25, 2009 Share Posted September 25, 2009 (edited) Have you cleaned out the air intake throttle body? See this thread. Edited September 25, 2009 by westslope Link to comment Share on other sites More sharing options...
