97 blazer 4.3 runs great at high revs, p0300 at idle only
Just put the engine back together after replacing a cracked head. Now I'm getting rough idle and misfire code p0300 only at idle, as well as the CEL flashing. If i raise the revs, the flashing stops. Also if I start the truck and keep the revs up, the CEL never comes on and seems to run smoothly. I have triple checked the crank to dist. timing and its dead on the marks. Any thoughts are appreciated. Thanks!
