P0135, P0155 w/ Engine Swap
Hi, I've got a 1998 F150 4.6 W, w/ 4x4 and automatic. We recently swapped the engine with a 4.6L W from a Crown Vic. The truck seems to run sluggish and is coming up with P0135 and P0155 codes. Since it has 168K on it, I replaced the O2 sensors, but the codes come back immediately on startup.
The freeze frame data also shows: Fuel Sys 1 OL-Fault, Fuel Sys 2 CL-Fault.
I'm thinking of cleaning the MAF sensor and the throttle body, but don't know if that would help.
I checked the fuses under the hood and all of them seem to be OK. Don't know which is for the O2 sensors though. But if that was bad it should show all of them being bad, right? Where should I go from here?
