Bad idle please help me???
Hi there i have an 86 gt, and when i start it, it idles real high like at 2000 rpms then in about a 1 min it will go down to 1500 then around 1000, then it will runn like that then about every few mins it will go up then down and keep doing that. i chaged the Spark plugs and i Chosed the Boush PLatnium 2 with the 2 sparkers on it. the wires are Aem and they look pretty new and i just put on a new MSD blaster 2 coil, what do you guys think it could be thanks alot.
Ernie
