February 18, 2005I have a ford f-150 and everytime it rains or snows my truck hesitates during acceleration. But when it's dry out my truck can fly like the wind. I have aftermarket parts like a K&N intake kit, 3 inch true dual exhaust with delta series 40 muffelers, hypertech programmer, and everthing else like tune-up things are all taken care of. Any suggestions would help, thank you!

February 18, 2005I'd look toward the electrical system. Either a connection under the hood, or spark plug wires, or something is not getting the proper connection due to the dampness ......
February 20, 2005I agree ,That Happened to a pickup that I use to have and I was told that it could be a sensor or something getting wet
February 20, 2005Did it set a code or turn on the check engine light?
If the light came on even for a short time there should be a code in the computer.
February 21, 2005No codes have been tripped, but something might be getting damp, I'am also considering the fact that I still have the old O2 sensors from my 2 1/2 inch exhaust instead of changing them to new when I welded my 3 incher on!
February 24, 2005the problem is its a ford sell it and upgrade 2 a ford
February 24, 2005sell the ford and upgrade to a ford...interesting
more like sell it and upgrade to a DODGE!
March 5, 2005If the O2's were the cause, you'ld have the problem all the time, not just in the rain ...... Figuring the vehicle's computer controlled, I'd look toward the Throttle Positioning Sensor (TPS) connection or the sensor itself, Or Mass Air Flow Sensor (MAF) or Manifold Air Pressure (MAP) sensor, which ever applies in your case, and their connections ..... Because these are the things that would cause hesitation ........
March 8, 2005I found out the problem when I tried to change the O2 sensor...the bung snapped right off..must have had a hole and it was getting wet. And why the hell would I trade my ford for something slower like a chevy or dodge...I race 5.0 mustangs there geniuses so get real! I'll keep continuing to make chevy and dodge look retarded at every stop light!
