I have to agree with fool4fishing. More detail is needed.
When was the last time you replaced the cap, rotor, wires, and plugs? And what brand/quailty of parts did you use? I have a '97 v6 that had similar symtoms, mainly after a heavy dew or on a raining day. Turned out to be a corroded dis. cap and a cracked wire. I didn't have but about a year on cap and wires, maybe 20k miles. I had used cheap parts and got what I paid for. I replaced the cheap parts with good quailty parts and the mystery was solved.

Don't over look the small stuff.

had a 01 v6 and it seemed like every year i would have to replace the dist cap and rotor, wether they were high price or cheep when they went bad it seemed like it would be higher humidity days,

ACDelco or the highest quality of parts from NAPA...........

I had that same problem when it got humid, especially last year when we had all that rain. Parking on gravel near grass didn't help either.

before they change the distribtor to plastic they used to have a little vent screen. and the caps was better quality i hate that new flat style they seem to burn thru alot and the clyinder short out or cross fire.

I went outta town today and it messed up again! I limped into a small shop told the mech. what was going on. He checked it out, low fuel pressure. Guess I got a bad NEW fuel pump. Goes to the shop Monday under warranty. Took 5hrs to go 70mi. 35-40 on the hwy ain't fun, stopping every few miles to let it cool off.

That thing is still under warranty?

IF THE TRANS. CODES WERE ALL CIRCUIT FAULTS YOU COULD HAVE AN IGNITION FEED CIRCUIT FAULTY, CHECK YOU IGNITION SWITCH I HAVE SEEN THIS ALOT ON THAT YEAR MODEL.

also check to see if the orings on the fuel filter lines are there, i have seen them fall off when replacing the filter and you wont even notice they fell off, might not even see a leak it will just suck air into the system.

It's in the shop right now. I told the mech to keep it as long as he needs to.
