Today I was working on the turn signal so I removed the battery (-) terminal. After I reconnected the battery terminal, I did the turn the key to on for one minute, turn it to off for 10 seconds then start to reset the DME.
After starting, now it runs rough at idle and when I go to hit the gas it gets to about 1500-2K rpm and won't go any higher. I got a DTC code of 1502 - "Throttle jacking unit spring test. Sort to B+ / above upper limit / rich mixture threshold."
Anybody know where I should start?
TIA!!
