Hey all I’m absolutely lost. Had this truck for a couple months and have no clue how to get running right. 1988 C3500 5.7TBI. Bringing it home it died at every stop the SES light came on. Code 22.
Changed out the TPS, but realized as I removed it PO had installed wrong (tab was on wrong side of arm) reinstalled original TPS - code disappeared. Since then done: cap, rotor, plugs, wires, CTS, cleaned IAC and still runs like crap. Dies at every light.
Today I checked timing (properly with EST removed) and it was 8+ advanced. I set it 0 and now I can barely get it into gear before it dies.
Any suggestions? I don’t want to run advanced, hoping to be a daily driver and carry my TC for summer but so far can’t even get out of garage.
ALSO PO out a Throttle body spacer on it (no chip). Could this be the issue? Know nothing about them, can I simply remove without modification?
Thanks so much.
