I've had this car for about a month. I can tell the previous owner was trying to troubleshoot this problem and gave up. new distributor, new plugs, new wires, all plastic connectors are new. Tested maf, tested and adjusted tps. It appears the previous owner removed a/c compressor and heater core. Car runs and drives, won't idle by itself until warmed up. Checked timing.. Seems to be on point. Very confused. Read about power transistor unit. Can't seem to locate it anywhere though. Any insight or advice would be appreciated. I noticed that plugs are ngk and oem plugs are auto lite copper resistors. Could the pre gapped ngk plugs be my issue?
