wired in some coolant temp sensor, it has 2 wires in the pigtail, ran one to ground and pone to the dark green and black wire. had to unhook the battery and take out the starter signal wire to get the knock sensor and block ground up where i could work on it. They had the block ground hooked to the KS and the Ks not hooked up at all. it seemed to start a little better but it was brief because it is getting late. i still think there is something wrong with the iacv because it is hunting a wide range of rpm. could be another problem. i will check all of the codes when i have a chance during the day some time.
