High idle in drive

When I am in drive or reverse the idle is so high that on hills I am unable to come to a complete stop... its like I have one foot on the gas and one on the break. is there something that I can try to fix before I spend a lot on getting a shop to analyze it?

It cost nothing to have it read at autozone..sounds like a fuel injection problem or firing improperly ..I am leaning more towards your spark plugs and or timing ..check also your distributor and rotor

SOURCE: '93 Aerostar-stalls while driving/scary-stalls in 'drive' at stops

Wow!!! Now that's a headfull of problems....
This could be a great many things...
Check these before you sell. I have a '93 Aerostar and can't live without it.
1. Check idle speed
2. Fuel filter may be clogged or water in the fuel system.
3. Choke improperly adjusted or sticking.
4. Distributor components damp or damaged.
5. Faulty emissions components.
6. Faulty or incorrectly gapped spark plugs/ Also check wires.
7. Vacuum leak at the carburetor/fuel injection unit or vacuum hoses.
8. On 1986 models, stalling during idle or deceleration may be caused by sludge in the throttlebody. (2.3 litre engine)
9. On 1986 & 1987 models with a 2.3 litre engine,hesitation or stalling during acceleration may be caused by carbon build-up on the intake valves.....I hope this helps!! Adios

SOURCE: 1990 Ford Probe 2.2 automatic stalls in forward, reverse OK

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.

SOURCE: my thunder bird has a high idle problem when im

I have had this problem with my 90' SC, easy check is to clean your IAC valve. Carbon build up prevents if from working right.

    Vehicle rolls back when idling in drive... will roll forward while idling in reverse as well


    I fail to get the problem

    If you have your foot on the brake-- it isn't going anywhere

    Obviously, if you release the brake it will roll in either direction

    The question is: did that not happen before-since you owned it-
    & have you never had that ,whatever it is ,happen with any other vehicle?

    Are you on a flat surface,if on a hill then the question is mute!

    Sebring 2007 shakes on uphill and reverse


    Sounds like a Transmission Torque Converter Clutch
    Try driving uphill with 1 foot on gas then tap the brakes at same time with other foot..
    IF Engine does NOT rev up, the clutch is bad.

    I have a 1990 chevy lumina euro that has a high idle when started and tends to die when coming to a complete stop. What could this problem be?


    have you disconected or changed the battery lately- the idle needs to be reset.
    my 89 regal had to be started cold -put in drive with your foot on the brake - then wait untill radiator fan turns on (open the hood first to be able to hear the electric fan kick on :)
    this somehow set the warm idle speed and the problem was gone :)

    I HAVE A 2001 AZTEK AND WHEN ON AN UPHILL INCLINE STOPPED, YOU MUST KEEP FOOT ON BRAKE OR VEHICLE WILL ROLL BACKWARDS


    This is normal, depending on the depth of the hill. This is frequent with standard/manual cars on uphills, they can roll back, but with automatic vehicles they usually have a small amount of throttle, (you'll notice this when putting your vehicle from park into drive with your foot off the break, it'll start slowly moving forward)
    Now on the hill, if it's a steep incline your car will move backwards, it all depends on how high your throttle (the car itself) is, and the incline depth of the hill.

    When first driving, I hear a high pitched whistling sound while my foot is on the accelerator. As I pick my foot off the accelerator, the sound will stop completely or after a moment or two and then return...


    I have the exact same problem, however reversed. My whistling sound stops when I accelerate and starts when my foot is off the accelerator. Frustrates me and am afraid to have it looked at for fear of the cost of fixing this problem. Have you since discovered what the problem is or was?

    Idle very low then turns off


    this is the cause.
    Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, 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.
