First thing to check is the base gasket on the bottom of the throttle body.if it's sucking air it will idle too high.if that's not the problem the you likely need a throttle posion sensor.

92F150 burning rich rough idle


Sounds like an idle air control solenoid, or coolant temperature sensor. Both of which will cause undesirable idle. A bad temp sensor will actually cause the idle air solenoid to not function properly (like running with choke on)

I have a 90 chev blazer that runs rough when i apply the brake ,it also has a high idle and runs rich .?


I would look at the vacuum booster control unit .
This is the power assiest for the brakes it runs off the main engine vacuum,
If its leaking inturnailly you would lose engine vacuum that would make it run rough when you hit the brakes .
Also if the check valve inside of this unit were stuck it could cause a vary high idle
Try hitting the brake pedel when its idleing high in park and see what effict it has on the engine speed .
If it changes this is for sure your problem.

Why does my engine stall when idling bf falcon only does it some times ?


Fuel Injectors
Use an ohm meter to check your fuel injectors (with the engine running), by removing the wire from the injector. Two metal prongs sit inside the connector. Set the meter for the ohm setting. Touch the red meter lead to one contact and the black lead to the other prong. The ohm resistance number should be the about the same for all the injectors. If any injector reading shows a higher or lower than average number, the cause will be a defective injector, which will cause a rough idle. A zero reading will indicate a shorted injector, and must be replaced. You can also use a stethoscope or a long handled screwdriver to place on the injector head. You should be able to hear a clicking sound, telling you that the injector is "pulsing." No clicking sound indicates a dead injector.
Carburetor-Equipped Vehicles
Examine the choke setting on a vehicle equipped with a choke adjusting knob or mechanism. Make sure the choke operates by opening slowly during normal engine warm-up. A choke that fails to open or sticks shut during warm engine running will cause a constant misfire and rough idle. A choke stuck in the open position will not allow an engine to warm up properly.
Trouble Codes
Hook up a portable trouble code tool for your specific Ford make and model. Look for any trouble codes that appear while the engine runs at idle. Write down any code number and look it up in a trouble-code manual. Most times, code numbers can pinpoint the exact system failure or miss in the engine.

Rough idle


Sounds like a automatic choke sticking....Take the air duct loose from carb..While accelerating engine spray bottle throttle spray in.....as the car tries to die...stop spraying...Repeat 3 or 4 times.....It will clean your injectors. Runs alot better...Remember....bottle throttle spray...not carborator spray

Rough Idle, Running rich.


Sounds like your automatic choke is giving you problems. Check to make sure the choke is operating correctly. If it ins not backing off as the engine gets to operating temp it will cause a rich condition and excessive black smoke out the tailpipe and extremely poor fuel mileage.

My 1998 Olds 88 has been stalling and running rough.


Check and clean the IAC valve. Idle Control Valve. Use brake cleaner or carburater cleaner . Remove the duct work from the air filter assembly. It is located just inside . Run the engine at 1200 rpms and spray the valve. The valve can also be removed and cleaned.
