runaway engine

I have a 99 XLTw a 2.5l and 5 spd. When I depress the clutch, sometimes, the engine will rev up. Sometimes it will idle on its own, sometimes I have to let up on the clutch to pull the rpms down and then it will idle fine. Supposedly there is a TSB about installing a "TPS connector high idle kit", buty I have been through the TSBs and can't find this article, supposedly article 00-3-5. Anyone know anything about this or has anyone had a similar problem? Are TSBs the owners responsibility or are they Fords? Les

ok heres what my truck did i'd pull up to a stop light and let out on the clutch and it would shoot to 3 or 4 grand on the RPM's after trying and fighting with for and 600 bucks later i finally figuerd out it was the TPS sensor 30 buck part thats what my problem was but it's something to do with ur air going into the motor or so i was told....it's eaither 3 things MAF,TPS Sensor,or the idler sensor all 3 of them should be around you throttle body or on ur intake

My 3.0L does this but I noticed it does it mainly when the A/C is on it will stay revved high in the 3K to 4K range after I push the clutch in and when coming to a stop.

its supposed to go up a little. my 4.0l does it. just think about it. the engine has this big load on it and you have a little bit on the gas. then you get off the gas and depress the clutch. theres still a little gas burning and the load is gone. common physics there.

now, those of you that shoot up to 3-4k are having problems. you may be running lean or wut wade said.

Nothing but your foot on the pedal should make it go that high. Replace the sensor before you go nuts.
