    My odd running cold issue.

    the engine has a closed pcv system that when you pull the oil cap off your car should have a drop in idle or die as a result of lost vacuum in the ingine. check to see if you have a good vacuum signal with a vac guage.18in.hG is the amount of vacuum you should have or atleast close to it. if not you may have an internal vac leak like i found on mine( it was the valves). I reground my valves and i am carefully hand lapping the valves to the seats till i get a good polished ring around both surfaces. i am just waiting for my new gasket kit to reassemble the engine and i will repost my results to here. my vac was way low only 6in hg - 12 in hg.we will see what happens.

    your AFM might be the culprit, check the conn. on the AFM,and see if the signals to it are present. if so then you may have a break in the wires. go back to the JY yu got the ecu and pull the harness for it out of the vehicle you recieved it from.

    my 76 280 is all stock and i am haveing a problen with it running smoothly. The car seems to run alright when you are driving down the road ,but then it will buck,or cut out, and then come back online. sometimes it will start to run from a normal idle and start surging, with the idle going from400-800 rpm's? this is driving me batty. i took it to a smog shop and the co was .3 and the hc was around 1200-1400ppm now i was told it was misfiring at all ranges. I changed the dizzy from a duel pickup to a single pickup and the car seems to run the same according to the EGA can someone please give me a clue or help me to figure out what may bne the problem?
