Idle Air Control hungry

Did the calibration minus the rpm check and seem to work for the IAC. Now getting intermittent EGR code. Thanks for the info though.

Idle Air Control hungry

Hello. Anyone out there maybe can solve why my 1994 350 is literally eating IACs. Have put 5 in it, the last one lasting only a few days before starting to throw code again. Thanks for your time.

Strange running habits, need help.

Sounds like O2 sensor bad. Without the reading computer has to "guess" thus the up and down.

Help!!! Shutting off issue

A shot in the dark but could be the temp sensor on top of motor. My '94 5.7L would not start with this sensor unplugged. ECM gets a reading from it. Don't know if it would shut down a running engine if unplugged with engine running as I didn't do that.

Limp home mode

Hello all. I have a 1994 Silverado 350 TBI. It runs great until you turn on headlights or turn on interior fan then it acts as if it goes into limp home mode, sputtering, lurching, wants to die and have to feather gas to keep it running, drinking gas. Any ideas? Input will greatly be appreciated.
