2003 5.4 2 valve rough idle, hesitation when stepping into it and low power no codew
I have an 03 expy with the 5.4 that has a rough idle, low power (0-30 in 20 seconds) and no codes I replaced the oxygen sensors, MAF sensor and the throttle position sensor. Could this be timing or is it IAC? Is it something else?- bydptrsb

Lots of codes cant fogure out cause
I am getting a lot of codes with rough idle and running rough under low load. Codes are p0174, p0300, p0306, and p2196. I know that the 174 is lean on bank 2, 300 is a random misfire, 306 is misfire on cylinder 6, and 2196 is stuck rich bank 1 sensor 1. I just can't figure out what is going on...- bydptrsb
