Clogged fuel filter and there was a muddy substance in gas tank. Jag guy said that the problem is recent but I am going to get the mud checked to see if it is from Florida (where vehicle came from) and if it is then it was an existing problem and the car dealer will probably take care of it. If the substance is not dirt then I'm pretty much screwed.
FJT, the reason we were off is because it pop two new codes when they had the vehicle.

What is long and short term fuel trims when car is under a load? Possible mass air flow meter.
