having problems with engine cutting out when wet.

[elpelodelfuego]

:rant:anytime after i wash or drive the truck when the roads are wet it will begin to cut out. it will still run its just if i give it too much gas it will start bucking and wont let me give it full throttle or even half for that matter. i thought originally i was having problems with my fuel filter or fuel pump but then narrowed it down to it only happening when its wet. otherwise it runs like a champ on dry days with no problems what so ever. i cant figure out what it might be and need some advice on where or what to look at that might be causing this problem? any advice would be very appreciated!!

Thanks,

Usually such changes under wet conditions correlates to problems or issues with the ignition system. Cap, rotor, ign wires. What condition are they in? When is the last time they were replaced?

honestly i have never changed any of them. its still has under thirty thousand miles and i figured they were probably ok. i guess beings they are twenty years old though i should really replace them.

Its wonderful that you have such a low mileage truck, but yes, the age and sitting will make things oxidize and detriorate. My guess would be that your cap and rotor are corroded, and the wires are arcing with the moisture, hence why its cutting out.

When replacing, use high quiality components and she will purr like a kitten. We have those parts in stock if you need. Let us know.

I would say Cap and Rotos as well. I had a supercharged Mustang that I was troubleshooting the same issue in. I changed a ton of parts without correcting the problem and what it came down to was a $30 cap and rotor set.

wait till its dark out tonight and take a spray bottle from like windex or 409 and fill it with water , start the truck and start spraying a mist of water over your plug wires and your cap, you will see whatever is bad light up and you will probably hear it also. easiest way to see if it is the wires or not.
