Rough idle
Really thought I got a smoking deal on this pickup. It is clean, straight, extended cab, 4wd, only 34,881 original miles. Has a very rough idle, and does not pickup acceleration easily. Read a few things on the problem, and today I replaced the PCV and hose. No difference. Idle air control next? Suggestions would be greatly appreciated. Wife biting my head off for buying a lemon.

Choose the proper sub-forum for your truck and repost there, with information about the model, the engine, the exact year and any history that you know of for the truck.

Driving me crazy
I have a 2010 f150 5.4 that is driving me crazy. I replaced the MAF to stop the check engine light. Now the intake air temp sensor is coming up. Replaced and is still causing check engine light. I also cleaned the throttle body and now it idles great but I can tap the gas and let off and it starts reving to 1500 rpm then falling to idle over and over. I can put in drive and it stops. If I put back I park it starts again unless I leave in drive for about a minute. Any ideas.
