changed air filter, now stalling surging at idle

jsfx3 · 10-28-2003, 03:42 PM

Changed the air filter on a 2000 Windstar. Noticed a high idle after first start up, but then everything seemed fine after a test drive. Now stalling and surging whenever sitting at idle, almost like computer can't figure out what's going on for air/fuel mixture.

Any ideas? Thanks.

Definitely check for air leaks, maybe the air filter canister didn't go back together right on the underside where it's not visible?

no idea how these things are related, but after listening to the engine closely, I found a cap covering a vacuum connection near the top centre of the engine in the area of the fuel rail.

replaced the cap, and everything is running fine.

What continues to be odd, is the cap occasionally coming loose / blowing off, but otherwise everything seems to be fine.

thanks
