Newbie
1994 Chevy c1500 5.7 TBI
I’ve been chasing and intermittent misfire and loping idle with my truck.
I replaced and tested the Engine coolant temp sensor
New EGR and solenoid.
New MAP sensor
New IAC
New TPS
Replaced all fuel lines, new pump, rebuilt throttle body (with gaskets) new regulator and injectors.
New plug, wire, cap/rotor. Orginal dizzy.
Timing set at baseline 0 degrees
Checked all vacuum lines, getting 18-19” at the throttle body.
-I have not tested fuel pressure at the throttle body yet, need to buy a kit.
-I do not know the condition of the intake manifold gasket either.
Anything I’m missing, I’ve been all over forums checked my truck over and over and I can’t figure it out.
