2007 Chevy Tahoe

Having issues with the truck. Replaced a disturbutor, truck starts and run, however the check engine light is still on with a po135 code.

I have a few questions as in where can I find the EST connector? What color is it? Need to reset the timming. Thanks

Sure it is a 2007 cause that engine does not use a distributor?

Most likely distributor is not installed correctly code is for cam/crank sensor corolation. Was code the original problem? Crankshaft checkout good? Was code cleared and it resets?

He said that a screw hole that was attached to the cap was broken off, replaced disturbtor as close as possiable. By sight and started running fine but MIL lit p1345 with timming light shows out 1/2 inch off scale.

That was the original problem code p1345
