Question about 2004 Ford F250
6.0L. Changed fuel filters. Didn't solve the problems. Surges at stop lights. Now if it idles to long at stop lights it stalls. doesnt always start back up. Press on the gas and it doesnt go anywhere (no rpms). Air filter in good condition. If I disconnet one side of the air filter housing, a hold a cloth with deisel, it starts right up. Could it be the fuel injector control module malfactioning? I have heard they have a high failure rate. AAA Auto said my alternator is reading 13 volts instead of 14 1/2. Could this have something to do with it?

SOURCE: surging while driving
This is a notorious problem with the Windstars. There are oodles of ground straps in them. Make sure they are all clean and tight. ESPECIALLY THE STARTER GROUND STRAP. If it's loose, the car may just die when you turn up into a driveway or parking lot or just go over a bump. If you notice the "Check Engine" light comes on momentarily, at the time of the surge or the engine kills completely, it's DEFINITELY the starter ground strap! My engine used to kill at odd times -- even when on the freeway going at 75!-- Then we'd go over another bump and SURGE_O_RAMA, the engine's running again or I'd restart it and it would be fine for a while. What's happening is the loose ground strap loses it's connection when you go over a bump in the road. The next bump jogs it back into the connected mode, albeit tenuous at best. All of the computer techs couldn't find the problem. It took a 70-year old seat-of-the-pants mechanic to make the SIMPLE fix. It took so long to find the common-sense mechanic, however, that the down-shot of all of the surging tanked my tranny, which I had to have rebuilt! AND then, after I drove away from the 5-star AAA BBB "transmissing" shop, I found that THEY HAD NOT TIGHTENED ALL OF THE GROUND STRAPS! I took it back. They had no knowledge of ALL 9(?) ground straps and had to take it to THEIR mechanic who tightened them ALL down! It's been 5 years since then and I haven't had another problem with it. RULE OF THUMB: EVERY TIME YOU HAVE THE VAN SERVICED have them tighten-down ALL of the ground straps! If your mechanic doesn't know what you are talking about, go find a new mechanic. Generally, the AAA "Top Shops" are your best bet. They fix things right the FIRST time. I still haven't found a manual that has all of the ground straps listed, by the way.

with the engine running lift hood and lisen for a vacum leak and check all your vacum lines. if no vacum leak can be found then replace the idle air control valve.
