Re: Car back to running like sh!#
So I assume, when cold runs great then once the car warms up the issues start?

Re: Car back to running like sh!#
Way to go a of testing but you got it!
Maybe advise for others is to test MAP swap right off if you happen to have one or a friend who does? How much is a MAP these days? |
