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