ok my cel light came on (p0118) and i found the problem replaced it with one from advance. but now my temp gauge pegs out on the hot side i can turn key on and it slowly creeps up to the red. i was worried but took temp gun and it reads normal. so i thought maybe had it plugged up wrong so i unplugged and plugged it up the oppisite way and now it throws the light again. what to do?
