Hi everyone, I'm Justin. Holy first post Batman! So here's the deal. I just installed a keydiver ecu and a set of 780cc injectors. I had a smooth running car before I did this, and now the idle surges between 1300 and 1700 rpm. I know that the throttle open/closed switch is good, and I swapped the isc motor with one that I don't know if it is good or not, but that didn't help anything. Does anyone have a suggestion? Thanks y'all.
