My 89 Gt has a mean stumble off idle! I recently put new spark plugs and ran some injector cleaner through it , but still didnt' fix it. Has anyone had similar problems?
Someone please give me a few pointers on this, cuz I'm stumped.
how old is the cap and rotor? my friend had a similar problem of idle, he had a hairline crack in the distributor cap. try that, always good to have nice clean terminals.
