Idle problems

[Skidzz]

Hey guys I've been having problems once in a while starting my car. Sometimes, usually when it's cold out it will die after I start it. I have to give it gas and keep on the gas for a while in neutral until it eventually quits dying on me and idles on its own. It rarely does this but I'm afraid it's going to get worse because I think it might be my in-tank fuel pump going out. What do you guys think?

I would start with fuel filter cheap only $15 at most. I think it might be clogged. Or you can order walboro 155 off ebay for $75.

Idle Air Control valve. Do a search on cleaning it or just replace the thing.

+1. IAC is probably sticking

Ok thanks. Where is this IAC valve located? Does anyone have a pic or anything to help me out? Also, if this valve is messing up, would it cause the engine light to come on? It came on a couple days ago but went off after about a day. I just had the car serviced and they went over with a fine tooth comb, so my engine light should not be coming on. Although it did go off right after i put gas in the car, so maybe the gas cap was just loose.

IAC.

heres where it is in case you dont know what it looks like. just buy a new one at vatozone or the Ford dealership. its a straight forward swap. shouldnt take more than 10min. new IAC should be around $50.

there is a pic for u . now take that sucker off. I prefer to u "gum cutter" but any other carb cleaner will work. fill it up and let it sit for a bit then wash it out and try to dry it good. should be as good as new.

when was your last tuneup including fuel filter,air filter& sparkplugs i have seen bad filters and worn sparkplugs do this. go to your local autozone and ask them to retrieve any stored check engine codes, any emissions problems stated above will show up with this check and you might want to run some sea foam from your local parts store thru your intake and in fuel system.

I just had my 60,000 mile check-up 2,000 miles ago. So i doubt its the fuel filter, because they replaced it. I guess ill try to clean out that IAC.
