Ok, when my truck is cold it runs just fine but when it gets up to normal running temps it runs rough. It is a manual 5 spd and when going through the gears it shifts fine but starts to cut out and lundge. Not horribly but like it is missing or something. I did a seafoam treatment this weekend where I pulled a line off of the brake booster and sucked up the seafoam and it didn't seem to change anything. What could it be?

No one can tell me anything?

Check your TPS and AFM.

And, check the coolant temp sensor. That's one of the usual suspects in temperature related problems. If it has gone bad, it could still be telling the ECU the motor's cold when it's not, and therefore signaling for more fuel than is needed when the motor's warm = flooding out.

Look under MFI systems for V6: throttle body/ VAF meter/ and ECT sensor for testing.

Ok, today I discovered that my truck starts acting like this when I press the accelerator further down. Not so far down too soon like I am giving it too much gas or too soon in the shift but when going through the gears if I let off of the gas pedal it takes off like I have the pedal to the floor. Does this give any more clues?
