-----Question-----
I have a two fold problem. First the engine acts like it is starving for fuel when I begin to accelerate, the fuel pump, filter, and throttle positioning sensor have just been replaced. It is a 4.9l. These are the only codes I pulled up out of the history, PO22,26,52,53,70,91,97,98, IO39,52 no acp, sir, pcm was a ?. Not for sure if there is a rev limiter on the car but sitting still and revving the engine causes it to act like its hitting on 4 cylinders. Second, during this I have lost turn signals, hazards, and brake lights. The parking lights work fine, all bulbs are good, the third brake light works, as well as the curbside courtesy lights on the front, not for sure where to check.
