Hi Richard
I'm going through the truck right now just to make sure all parts are working. I understand that the EGR solenoid would not impact the operational status.
Currently, the truck starts and runs only when i'm actively feathering the throttle. If I let off, it runs for a second or two then dies. If I try to simply keep the RPM at a certain level, it dies. I have to actively rev it.
Next step i'll be taking will be measuring the fuel pressure coming from the pump. I'm concerned about the pressure regulator on the TBI not working properly. I have one from a 93 chevy caprice that fits and is supposed to be the same fuel pressure, so, i'll try that and see. (part# GM Part # 19143609)
I've done the reset of the IAC motor and adjust the idle screw. Actually, you might know this: how much should the idle screw be in when setting a base setting?
I appreciate the help.
The manual I got from here does show much.
