Codes. Help please
1999 f250 with 5.4. Put new head gaskets on it and got it back running. So far I have put new bank one sensor one 02 sensor and new mass air flow. Truck runs good then bogs for a second and straightens up. Current codes are p1142. P0135 and p1151

Mine was giving me the same code but for the other bank (minus the fuel restriction one). I replaced the upstream sensor (actually both) and the problem went away.
PS, those sensors are a lot cheaper on Amazon than your local parts store. I got 2 of the same part, for less than 1 and free shipping.

I had the same codes going on my 04 CTS, come to find out where the header pipe and the exhaust pipe met, the gasket was oh so slightly leaking, just enough I guess to suck in air and cause a lean condition.
