is it missing?

Hey guy's and gal's,

New to the forum but have been reading about a lot of interesting things some do with their trucks. On my second Tundra, drove the first one to 317000 miles and was purring when I let her go. First guy looking took her home, love these Toyota's!

Anyways, my 2010, 5.7 is giving me some grief. Had a PO442? code a few months ago and it was bank one secondary pump/valve. So I replaced the valve and inspected the pumps, (they looked brand new so I didn't do anything with them) ran fantastic again for 2 days, then code came back. Took it in this time as I needed to go back to work and they replaced the bank one pump. (O'Rileys remand!!) OK, all was good as it worked to get the light out but seemed to run rougher? I don't know maybe just me but with 140,000 on her I went ahead and cleaned the throttle body, MAF sensor and installed new plugs. It's been two months or more and still idles high, when in traffic I have to keep on the brake and still has what is a bit of a miss under power. I pull a 27ft travel trailer and have noticed I "have" to hang my foot into it over the coast range now where before that was not the case. Almost needed to back out of it or run people over lol

Any ideas out there? suggestions? I am thinking the pump should be replaced with a Toyota pump and most likely will do so but "is" that the problem??
