I have a 73, 1.7 liter with everything new or checks out OK on the Fuel Injection. One culprit left the CPU. I'm in El Cajon Area of San Diego. Any rebuilders, besides sending to PelicanParts?

QUOTE(kpax914 @ Oct 5 2014, 08:17 PM)  Anyway I hooked up the 2 CPUs and same dproblem with the idle as mine. Advance the throttle and problem goes away. Thankx Kpax914 You plugged in TWO OTHER ECUs and the problem is still present so you think it is the ECU? To ME that means that the ECU is NOT the problem, or my troubleshooting logic has taken a turn for the worse. |
