Hello And thank you for using Just Answer. Have you checked the plugs,cap rotor ans wires. Do a wet test on the cap and wires. Also on cylinders 7 and 8 they are close in the firing order and sometimes the spark jumps between the two causing this issue. Check the routing of the wires on these cylinders and look at the cap closely for cracks. Jim

it sounds like it is sucking in the intake we have ordered a egr riser value also just have not got it yet

 

Ford Mechanic: jimchill, Ford Technician replied 8 years ago
Can you explain"sucking in the intake a little better". I would check the intake for leaks and clean the throttle body plate as it may have a carbon ring and also remove and clean the air bypass valve, this should improve the idle qualitya nd cold start quality. Jim

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
