I finally got the ignition and fuel pump hooked up on my 76 2.0 L and the engine cycles between reving and stalling when I hold the pedal down to get a fast idle. What do I need to be checking now?

Can you take some pics of this potentiometer you're talking about? There was a trim adjustment on the ECU but not one in the wiring harness. May have been some bandaid by the PO.
BTW, how is the normal idle? Is it smooth? How does the engine run if you try to go to a high RPM like 2k, 3k? Does it run good enough to drive it? |

QUOTE(Spoke @ Jan 3 2013, 08:25 AM)  Can you take some pics of this potentiometer you're talking about? There was a trim adjustment on the ECU but not one in the wiring harness. May have been some bandaid by the PO. BTW, how is the normal idle? Is it smooth? How does the engine run if you try to go to a high RPM like 2k, 3k? Does it run good enough to drive it? the idle is smooth but so low that it stalls out after 3-5 seconds. If I start it with not pedal and get it idling then try to give it some gentle pedal it immediately stalls out. So, I can't even get it out of the garage yet to try it out. I had it running enough last night with short idles to get the engine warm enough that coldness should not have been the issue. (IMG:style_emoticons/default/sad.gif) |
