my check engine light came on yesterday and i checked the codes, i got a code 11. Now i know that it means that it's the ecu ground, but i cleaned my ground and checked to see if they were secured and they are. If i checked the ohms on the ground, what are they supposed to be at? and also my main relay gets really hot after the car has been on for a while. would this be a contributing factor to this problem? any info would be appreciated. I have a 1986.5 n/a auto if that helps. thanx for the help.
