My new 80td has an issuee where the glow plug light stays on for like a minute,is this an actual glow plug issue? I have been a gentleman and have been waiting as not to disturd the glowing process but im not sure if i should be waiting?
Can i upgrade the glow plug relay to later style? is it any better? this 80 td is a whole different animal than im used to.
Help
