Rough Start in cold weather

[Pickupman_69]

I had this issue last winter also but once the warm weather came it was fine again.

if the truck has been sitting for 8 hours onward in cold weather when I start it it almost stalls and chugs along. this can be resolved by giving it gas but im sure there has to be a better fix than that.

any ideas to what it could be?

My trac has an engine block heater, very useful down here in Miami.

cluster Im jealous,but im not talking miami cold. im talking canada cold.

I know it needs a new battery but it turns over fine just sputters to get going. and this even happens when its slightly under 30f which def wouldnt be enough to affect gas and oil.

I'm just joking about using the engine heater, it's useless in Miami, it never really gets cold here. Perhaps you have a leak in your intake manifold gasket. Check for vacuum leaks also. Is your check engine light on? Maybe your idle air control valve isn't working properly, you could try removing it and cleaning it with some electronics cleaner and see if that helps. Don't put it back on until its dry of all the cleaner.

check engine light has been on apparently some emissions parts,its a canister or something I forget what the mechanic said by the vent valve.

Ill have to check for the vaccum leak,it did it again tonight and I have no idea why it only does this just below freezing.

thanks

sounds the same canisters i used to make(mahle filter systems north america)...we made "carbon canisters." its a can(though not all of them resemble cans) filled with carbon pellets that saves up gas vapor so it can be burned off later instead of leaking out into the environment(good for emissions). the carbon cleans the vapor. our ford part had 3 chambers on it(meaning the vapor got cleaned 3 times before it was returned for burning. it should have an input and output and possibly a purge tube on it. they are made to hold pressure.

sounds like what my mechanic talked about, but it was a three hundred dollar part so I decided not to replace it
