You seem to have the dreaded IAC ( idle air control valve) problem that Ford is famous for. The first likely suspect is the IAC valve itself, but there can be other contributing factors. With the amount of space I could not do the subject justice, but there are many online Ford forums that address this problem. I think the Ford price for the IAC is around $100. The Autozone cheapie is around $50. I think the Ford unit is a better part, but you have to make your decision. Do some reading up on the subject before buying any parts though.
Good luck.

Idles roughly, then low when stopped or in park, then dies. Decreasing gas mileage. Slow to accelerate


Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

Sounds like your idle air control valve, after time they get dirty and cause low and/or rough idle. They also cause vehicle to just die when idling or taking off from a stop sign. Unforntunately they cannot just be cleaned, as this ruins the finish inside of the unit. Check your local parts store, they can be pretty expensive units to purchase; however, they are usually fairly simple to install, good luck! :)

This condition can be caused by a sludged up idle speed control valve and a dirty throttle valve, do the following procedure to correct this, if it still doesn't repair the problem have the idle speed control system tested by the dealer.

Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1996 VW Jetta with 2.0 engine. Dies when slowing from high RPM


Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.
