Ford even noticed (what we thought was the final cause of the problem) that one of the fuel injectors had a drip leak and said that would cause the problem. Said the drip was loading the cylinder up with fuel and the computer was leaning the bank out to compensate, which caused it to stall until the excess fuel evaporated or was burned... replaced it.... no change.

He tested the fuel pump as well and said it was fine and noticed nothing else on the computer tests that indicated anything was wrong.

As of right now the only time it really does it is when I really get on it.. But overall.. this is really starting to get on my nerves. I'm gonna take it and put it on their computer one more time but if anyone has any other ideas.. i'd appreciate hearing them.

You need to know what the fuel pressure is doing under load, Not just sitting. Tape a guage to the windshield, Drive it with a scanner that shows fuel pressure. But somehow find out what fuel pressure is when the problem occurs.

As far as the light, its always on due to no cats... so i can't check anything with that... yes i've been too cheap to get the MIL Eliminators.

You can still check the codes and see if there is a different code then the normal one caused by not having cats. The ECU will store additional codes even though the SES light is already active.

Throwing things out in the wind here; Maybe something electrical or maybe a vacuum line off somewhere?

After talking about this in person with Mike yesterday, it sounds like a fuel system issue. I think he is going to replace the pump/sock/filter and see what happens

Yeah, thats the next step. I'll keep you guys updated.
