Fuel pressure at idle is totally different than under load. It needs to be checked while driven or on a rolling road dyno to simulate load. The fuel system is really tempermental if the pressure is not correct.

I think they checked it at idle the first time and it was at 52lbs. I don&#39;t know how they checked it the last time to get 44lbs. They never mentioned about the fuel filter. So maybe thats causing the bad reading and causing the pcm to adjust fuel and cause the bogging down. In reply to one of the other posts, there is no back fire. I feel I am going to get a huge repair bill after all the diagnosis. Thanks keep the ideas going I will relay them to the mechanic. The Sub will sit in his shop until Monday.
