2008 ford expedition, its chugging at all different speeds even idles funny some times. It happens very sporadically, its very slight but noticeable.


Replace/check plugs wires and coils. Helps to use a spark plug tester to isolate a misfire. Next check/clean/ and replace maf sensor, idle control valve, and egr tube/valve.

My 2001 Ford Expedition just had it's spark plug changed. The mechanic says he had to take the intake manifold off and therefore replaced the gasket. Since then, my truck runs horrible! It actually idles...


Take the intake off to replace the plugs? Thats a new one. Check if that vac line to the egr has vacuum on it at idle, it shouldnt. If it does, find out why. Make him fix it, if it ran good before. Now there are times that the coils go bad (real common). and sometimes just taking them off and on will make them go bad. But you may have more problems.
