Re: low rpm miss

How many miles are on the car and how many miles since the last plug, plug wire and opti change?

Re: low rpm miss

Most of the time I would say wires or plugs will do this. I had this problem for months before I noticed I had 2 really bad looking wires. I couldnt see they were burned through till I was replacing them.

Re: low rpm miss

If you have the original plugs in there, i would change them also. Does it miss under load, crusing or just all over? All your vacuum lines connected with no cuts or splits in them?
