Replying to: euphonium (Dec 01, 2008 10:46 am) I wanna say like 5000+ miles maybe... I purchased the car this past May. I changed the plugs, fuel filter and gave it a oil change. I was thinking it was the plugs but in the past when a plug was fouled it would throw a code that theres a misfire. I haven't started it in a couple days due to someone saying it could be the harmonic balancer and it could take out the crank seal. I was going to change the plugs again but I'm not sure.
