My oil pressure gauge has been non op for about a month (right after a heavy rain). I wasn't worried the oil was there and the idiot light still worked (two diffrent circuts but the same sender. After washing my car tonight I now have a semi blinking oil pressure light.. at idle it's somtime on full sometimes off... off idle it blinks randomly.
so how do I check the pressure.. should I just go ahead and replace the sender or ?
