Question about 1990 Ford Probe
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

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

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.

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.
