I have a Studder / skipping while on throttle. The van has high miles with 210k, 5.4 triton motor. There is no check engine light to scan? The first thing I was going to try is new coils and spark plugs. What do ya'll think?? I'm was going to post this on F250 section as well. Thank you!

 

Certain conditions must be met for the misfire monitor to run, and if they are not present there may be no record of the misfires..
