High iddle in 95 escort while in drive high rpm when put into park
Son pruchased a 95 escort has low ks car ran fine in jan 08 when he put it on the road but after a week or so he noticed the rpms were running high on one day we stoped at the bank and when he put the car into drive the rpms shot up past 3 he shut the car off after 10 min or so when he was done the car started up fine, it did this a few more times but then in the summer with warm weather he never had a problem, now that the weather is getting cooler the car is starting to rev high again this time you can feel the high rpms as you are driving and when you come to a full stop at a light or intersection it feels as if the car just wants to take off and when you take your foot off the break the car takes off as if there is cruse control car is not equiped with cruse contron, he reasently replaced the timeing chain and fan belt, just last week he had to stop and get it checked out at a guarage the only way he could explain his problem was to stay in the car with his foot on the brake and not put it into park the machanic did what he could as once in the shop the car would not do what he had showed him he cleaned the o2 intake and something else said it was full of carbon but now the car is still having issues and the check engin light comes on and off not sure if maybe there was a recall on 1995 Ford escorts for any kind of rpm issues but every time we take the car into the machanic the car will not do what we have discribed can you help ?????

Recheck the timming marks on the timming belt sometimes when the release the belt tenisioner it go's off in cam timming this changes the vacume on the low end and this could be your problem.
A Smog station can somtimes locate if youre dealing with fuel or timming. But I think this is what it is. C69

Your caption says misfires at high, then you say low? You have a 95. Lots of miles I assume. So there are several things that would cause misfires at high and low. First is timing chain/belt, sloppy. Second, would be the valves and rings. Valves worn or bent, not seating right. rings just worn out, not holding compression. Do a compression test and see. Low speed or idle misfires can be from vacuum leaks. check hoses. Low and high rpm misfires can be from ignition problems. Wiring, coil/s, ignition modules.
the idle RPM is too high or its just too cold, how cold is it outdoors? idle speeds cold can be about 1500 RPM/ cold. and will ****. it jerks because you are taking 0 torque from engine and the sending that to a stalled rear axle. this cause a ****, that is why the park lock out requires Brakes on so yo dont run over things.
When a crankshaft sensor has failed or is failing, certain timing problems will arise in engine function. The engine may start normally in some cases, but will cut off after a few minutes (or seconds) of operation. More than likely the engine will be unable to start at all. Since the crankshaft sensor is responsible for engine timing, the driver may experience engine backfire or irregular rpm function, if the vehicle starts at all.
For the high rpm part, have you looked to see if there is a vacuum leakage or possibly a fault in the Idle Air Control motor.
With overheating since jeeps are single belt driven it could be possible the fan is starting up when driving slow or parked because the belt is moving right. Or look for leaks in the coolant maybe it's not getting enough coolant.
fluid in the glove box though, can you be more specific with that one.
