Q-jet M/C Solenoid

Jun 15, 2004 2 Replies

I'm trying to troubleshoot a sudden power-loss and surging/bucking under load problem on my '86 Camaro, 305 4BBL, and was wondering if I could safely disconnect the M/C solenoid connector from my Quadrajet (E4ME) and drive around like that to see if the ECM isn't at fault?



My understanding is that the computer energizes the solenoid and leans out the mixture in the primaries when necessary so if I disconnect the M/C solenoid connector at the top right front of the carb, it'll run rich all the time. I'd just like to see if the computer isn't mucking up the car. If not, fuel pump is highly suspect. Well, please let me know if the car will run OK if I unplug the cable going into the M/C solenoid? Thanks in advance!

I agree. Probably an old tired carburetor in need of a good overhaul.... Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 26k orig.
