stalls at a stop sometimes
my 84 f-250 with 351w stalls in gear at a stop sometimes, mostly when its wet outside, it can be 20* and run fine but after a rain you can count on it to die. it runs rough, like the idle is going lower then dies. if you put it in neutral it doesnt help, but if you give it gas it smooths out. also when you take off it isnt smooth, it like jerks like it has sudden bursts of power. then the rest of the day it is fine.
how can i check the dashpot?
how about the tps?

I don't know about checking the Dashpot and TPS, but i think your TFI ignition maybe on its way out. Sounds like when it gets moist it flips out on you, i've had a friends car do this to me too, we replaced just about everything, untill we changed the TFI module and Coil..that was the fix for us.

I have seen this over and over. I have a 65 mustang and tried over and over to get rid of it. What it sounds like is carb icing. My mustang does it because when I first got it, I didn't know any better, and ripped the metal shroud off the passenger side exhaust, and bought a chrome aircleaner. I never could get the problem to go away, and then when I got my truck and modified it, the same thing started to happen. That's when I realized you have to have the factory aircleaner with a functioning flapper door hooked to the exhaust manifold to draw warm air to the carb. I hooked my truck back up original, and the problem went away. I will just live with the mustang doing it, but not my truck, when it's pouring down snow outside and I depend on it to get me somewhere, or I want my wife to drive it and not hassle with holding the brake and the accelerator at the same time. I have been debating about putting headers on it, just for the fact the 302 manifolds don't fit right on the 351w. I have been formulating a plan to somehow make a sheetmetal shroud to go around some of the header pipes to retain my warm air intake for the aircleaner. I sure don't want to lose this feature.

that could be true, i removed the valve and duct, but the problem is that it only does it once. at the first stop of the day it will run nice then at the next one run alittle rough but not die, then at the next stop it will die and will start right up. i think im going to have to make the heat duct for it b/c today it snowed and when i stopped somewhere for 3 hours i had to crank it alittle but then when i stopped about 5 minutes from the first place and waited 5 minutes i had to crank alot.

[updated:LAST EDITED ON 22-Nov-02 AT 05:51 PM (EST)]It gets so bad on the mustang, sometimes the throttle will stick. The frost builds up on the butterflies and it won't let the throttle close. Usually after the first stop, heat from the engine will rise and warm the carb up. Sounds like you have a mild case and a little bit of warm air will cure it. Some vehicles are worse than others I guess.
The only other problem I have had that occured during wet weather is, I had a vehicle that when it rained, it wouldn't start at all. Dry weather it would start and run fine. I stumbled upon the cause of this when I happened to take the high tension lead off the coil. Down in the coil it was all green and corroded. I put a new coil on and the no-start problem during wet weather went away.
