86 sr5 misfire w/lights on
 

86 sr5 22re that misfires only when you first turn on head lights or high beams, or when the stereo is on. also it will misfire when the blinker blinks. I cant seem to find the issue.

truck runs great otherwise. fresh rebuild, but it had this problem before. I know its some wiring issue I just don't even know where to start looking?

problem solved.
 

problem solved simple grounding issue. I had removed a bunch of old wiring when I rebuilt, he motor and never reground everything.
