New to forum 91 fox 5.0 misfire at high rpm


New Member
Purchased a car in the condition that it was there and put a TF out and got rid of the high rpm misfire now and you’re barely into the throttle it sounds like a misfire but I think it may be a EGR problem car was a basket case and now is a work in progress driving it every day has been the most help I believe that way I can change and working tune I will keep posted and give more information when I’m not at work thank you for the reply
