Did this happen right after your "Tune Up"? Sounds like you have an intake leak. Check to see if all the vacuum hoses are connected - or if there are any hanging loose - even check for cracked hoses .
If you can follow your air cleaner tube to the engine, make sure all the electrical plugs are connected to the throttle body , and that nothing is keeping the throttle stuck open.

Sounds like you need to take it to another mechanic?

Got a 2002 ford windstar. the vehicle is in gear but jus keeps reving up. them shut it off than back on n it will drive foward and reverse than stop n when tryin to drive again it will jus rev up again n...

The transmission filter is stopped up. Change it and add some new fluid and "trans x" conditioner and hope for the beat. Otherwise you need a transmission.

Have the cat converter check for internal failure. Check for small rocks between the exhaust pipes and the heat shields.

Will my car over heat if my radiator coolant fan not working

Yes, it will be fine while driving over 40mph but when you stop, air will not cool radiator by it self and the water will reach high temp....
You can drive it for a short time but as soos as you see temp rising you need to stop and open the bonet!

When I start the explorer it will reb up and the die. It takes forever to keep it running then it will bog down while driving it. Sometimes it will even quit at a stop sign.

Sounds like you need to change the fuel filter. If the problem persists, have the computer scanned for trouble codes in order to pinpoint the problem area.

Idealing issues

Needs a tune-up:

Spark plugs and wires and distributor & rotor.

Do wires last... the others probably need to be done.

Hope this helps!

I just had the same problem. Check the catalytic converter. It took me forever to get over 30 or 40. Drove everyone in the road nuts. They initially thought it was the transmission. Not so, clogged catalytic converter. I got it tuned up and the engine runs fine. Wish I could sasy that about everything else on this lemon!
