It's been doing this for a bit now. Temp is about 1F out and it does it anytime it's remotely cold. One of the battery cable ends is very corroded so I think it's that, but just wanting to make sure. Here is a video of what it does. Sound it crap I apologize. But it basically bounces from 500 to 1k rpm when idling. When I brake the lights dim. Recently since it's been real cold it's also died while in drive.

Please, explain how a Chevy idles in comparison.

It was a joke. You know this is a Ford forum.....

Is this just when it's cold (engine) or does it do it when it's warmed up? Anytime you're idling below norm you're going to have lights that dim as you're not running enough rpm's to charge the system.

You could easily have a fuel pump that's struggling with the cold temps. Couple that with plugs that may not be sparking properly because of low voltage/poor cables, makes sense to me.

You have an issue with a battery cable. Fix it.

It does it anytime but it's more prevalent in cold than warm weather.

A corroded cable can cause many issues with the truck, including idle issues.

Resistance added into the circuit from corrosion lowers the voltage, which in turn increases the amperage draw on the system. If left too long this can cause damage to the electronics in addition to any acute issues.

vacuum leak or IAC stuck?
Intake Manifold gaskets causing a vacuum leak?

As stated above, I'd replace that cable/end asap. You're not helping anything by leaving it "very corroded." Just going to cause yourself more trouble in the long run the more you wait.

Ditto on Sonic twice -


replace the corroded cable...your truck is 16 yrs old and you're asking for trouble


greg, take a chill pill or if you're in 1 degree weather, step outside
