Help, running rough
I have a 2000 F150 4x4 with the 5.4 engine. Yesterday I pulled up to a red light and it was idling fine, then suddenly started idling rough. I haven't checked codes yet, the service engine light was already on, don't recall the code # for that, was MAF problem though. It idles really bad, runs good on the road, but when you let off the throttle, you can tell it is missing or something. I am about to go get codes read and see if it does it when cold.
Ok, codes were p0174, p0171, p0122, and p1120.
R&R the TPI, reset the codes and no problems as of yet, gave it a hard day yesterday, will do so again tomorrow and see what happens.
