Hey all, I have a 98 1500 with a 350 that had 90k miles on it. We just rebuilt the motor; same crank, bored .030 over, new cam and lifters with a 110 degree lobe center, the MPFI fuel injection we just installed, with new plugs/wires/cap. Anyways so I have the CRP123 scanner which we used to set the timing to 0 degrees on the distributor (which we are using the original one that was in the motor, the gear is not worn on it at all) and we are getting a massive surging and stalling idle; the retard on the scanner stays between 0 and .03 degrees so I know it isn't that.. We had thought it to be the IAC valve so I cleaned it up and it helped a little but not much, so I went and bought a new one and installed it with no luck. I've been reading to change out the Crank Sensor but I don't want to go just throwing parts at it like I have been so I wanted to ask you guys first.
I'm stumped here and really need some help, if anyone could give me some advice I really need it. The CEL is off and there are no codes to scan for but I want to say we got the code ONCE for Crank Sensor Circuit High Input but we haven't gotten it again.
[EDIT] I forgot to mention I've sprayed starting fluid all around the upper/lower intakes and there was no change so I don't think its a vacuum leak.
