2006 f150 4.2 hard start and idle rough
I just bought a 2006 f150 regular cab short bed with 100k miles 4.2 v6. The only issue i have is when i start it it cranks and turns on but starts to act like it wants to die ans gets to 500-600 rpm then jumps back up to 1200-1500 rpm. Every time. In Park it will also feel shacky but in Revese or Drive its ok. I pulled codes and p0442 came up but i bought a new gas cap and the idle did improve a little but not the starting issue. The code hasnt come back after i changed the gas cap. Could it be the IAC? The plugs look new but i dont know if the coil was done. I can only assume he did the spark plugs and wires. Hoses look good around the engine aswell.

New to the site and 2006 F150 s,
i have the same issue, my bud hooked it his code reader and told me IAC! i ordered one for my 4.6 V8 and they found me the part. to my surprise i couldn't find the IAC on my truck. youtube videos Shows 06 having one. Rockauto shows a listing now i read this post and you confirm that my truck does not have an IAC. I must admit this is confusing. wish i have looked here first, hope they take it back.
thanks Guys
