got the plugs changed. put in autolite 26. both places were out of the r45ts. new cap and rotor. not I do have a question.
on the egr solenoid. on the two vacuum ports. one has an orfice and the other does not. does the egr valve hook to the orfice port or open port. I had mine from the tbi to the orficed port and the open port to the egr.
and evidently I have forgotten how to log with tunerpro. guess its been a long while. need to find that tutorial again and read it.
and today I was given a 1227747 ecm out of a 1992 chevy 1500 with a 350. are the 7747 any better than the 8746 ecm's?
