Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Welcome. Did you just remove the distributor or are you just checking it?
yes had center head off to fix water leak
OK, did you mark the rotor and the distributor to see if you got it back in on the correct tooth?
BAsically, does it start and run /
start and run good bu t light light stays on have a scanner have tried turn off light no good comes back on
Ok, the fine tuning is done with a scan tool. YOu need to look at the CMP retard. This is the relation between the cam and crank sensor. It needs to be +/- 2 deg for the light to go off. Find the number, turn the engine off, make the adjustment, start the engine and then rev over 1000 to update the reading.
can i check tdc timing on this engine with light
No, it is completely computer controlled so it must be read with a scan tool
YOu an try guessing, rotate a bit, clear the code and see if it come back.
