Wet Weather

I have a '94 F150XL with a 4.9L inline six. In wet or moist weather, if I don't let her warm up for 15 minutes the truck has starting problems and "stutters" (hesitates) above 50 mph and when going up grades and I have to back off the accelorator. I'm going to give her a tune up (new points and plug, etc) but my question is has anyone else experienced this and if so how did you correct it? Thanks.

Good luck on replaceing the points. It's probably bad wires. Here's a fun way to test. At night, run the engine with the hood open. If the wires are really bad, you will see it. Take a spray mister full of water, NOT the hose, and spray the wires from a little ways away. Instant lightning show.

I find that alot of my stuttering in the wet weather is from water getting in the intake. it splashes a little bit in there and the truck runs like a training car you see at drivers ed. Idio posted a cheap fix for it, by turning the air cleaner around, and making it a snorkel. well you dont have to make it into a snorkel, but you could just make it like a ram air intake.

i have the exact problem. i was told it could be a cracked distributer cap. i'm going to replace the cap, rotor, wires and plugs this weekend. i think somebody said it should be under 100 bucks for motorcraft.

the truck runs fine when its warmed. the warm engine burns all the water off. it looked like i was just learning stick when i took off. the first time it happened i thought my truck was going to blow up. i was on a one lane road w/a whole line of cars stuck behind me going about 10 mph. it would very slowly accelerate and then all of a suddes i was fine.

I had the exact same symptoms from my truck, damp rainy days it would stutter for a while upon initial acceleration, and then went away. In my case it was the distributor cap. Good luck

check all your electrical connections (ignition wise) and plugs condensation will build up or w/e when its humid or rainy causing your condition (tune-up will usually fix it) ;

Fixed!!!

The thing finally died (wouldn't start). Myself and a buddy changed the distributor cap, rotor, spark plug cables, installed new plugs, bought and installed a new battery (the one changed out was OLD) and changed out the starter (totally dead). Now she runs like a top. Oh, yeah did all this in the train station in Michigan City, Indiana. And froze my a** off.
