i have an issue with my car when it idles. this started out of nowhere.
its efi, 93, a9l ecu, manual trans.
if it idles, sometimes for 10 seconds at a light or for 2 minutes in the driveway. when i take off, it has a large hesitation. it acts as if the car is loaded up on fuel. it gets popping from the exhaust, big resistance to revving, and feels like it has 40 hp.
this problem got BETTER after my tuner thought my ecu might be failing. i swapped my a9s for a new a9l. the issue did get better. the car will still do this sometimes, except it will now clear out if i get into the throttle.
with the a9s ecu, it did this a handful of times and would NOT clear out. my only solution was to shut it off and start it right back up. the problem was immidiately gone. any thoughts?
i have switched ecu's, had a custom dyno tune, cleaned maf element, no codes. it does this when its cold as well just under normal acceleration, i can deal with that. the issue though is this happens under full operating temp as well.
