Problem Description and Possible Solution
If you experience cold starting problems, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steadily and run when the accelerator pedal is not pressed.

Truck runs fine when warm, but has trouble starting when cold and holding an idle. Anything above 3000 RPMs and it stalls outright. Other random times during idle it will mysteriously sputter and cough, then die. Already spent $100 replacing distributor cap, coil, rotor, plugs, and wires (everything except spark plugs, because I was lacking the correct tool). After doing work, Ranger ran fine (because it was already warm). Next day went out to start it up and go to work, but it barely made it a block down the street, died, and wouldn't start back up.
92 Ford Ranger stalls if I let it idle for even a minute. If I come to a stop, the truck may stall or backfire when I hit the gas and it may not get any acceleration. The truck runs fine in the higher rpms or on the highway. I'm forced to rev the engine at stops to keep the truck from stalling. The problem has been getting progressively worse
doesn't like the cold weather. idles very low and won't stay started. when it warms up, it's fine
Truck hard to start when cold. Replaced aic valve mass air flow sensor and battery. Truck still stalls and lacks power.
Won't start when the weather is cold. Turns over and gets gas but won't start. Later in day when it warms up it will start.
Engine begins to rough idle while stationary, at a light etc., but If the gas pedal is given a quick tap it will smooth out and continue to run, otherwise it will stall. Restart has not been a problem so far and the number of occasions has been minimal. Has not been in for repair yet.
I'm having trouble starting the engine of the vehicle difficult, especially in the morning. There was a lot of smoke coming out of the exhaust pipe after switched on. Every day I found mutual radiator water is reduced and the need to fill at least 750ml. Similarly, the engine oil needs to be filled every weeks since decreased. Are the problems experienced my vehicle and tell me what to do for my vehicle? TQ. Type of Engine 2.5cc model 2003 Ford Renger.
Occasional high idle at startup turned into stalling at idle. It starts right back up but if it falls below 2K rpm, it sputters and stops.
Will not idle when cold. After warming up for 2 minutes...all is well.
Replaced the ECT sensor and sender both....cured the problem for all of a day.
Hard to start cold, rough idle, won't stay running until warms up..
Hard start rough idle and dies at stop light intermittent
Will not idle at cold or after engine warms up.. Sometimes engine will barely idle but surges terribly
It takes about 4 turn overs to get it to catch and start
When I start my truck it won't idle I had to push the gas take it around the block come back and it idles what could be wrong
i have replaced idle air control valve. this has not fixed the problem. still revs at 1.5 rpms.
Stalls out consistently when starting until warmed up lately..now will only try to start and won't keep running. Fuel pump is working, plenty of gas.
will not stay running after starting when cold.
It'll start but won't stay running bought it for work commute only have had it for two days.
Just bought this nice little beater 5 speed rwd. Runs fantastic, while I am shifting up or down, smoothness. Some belts squeaking, no worries ... But this idle stuff.
Turn on the vehicle, clean start hot or cold, but it chokes itself out, the engine does not get air unless I give it. It will go down near 0 rpm, the computer will signal no air getting through, it revs up to keep itself alive, rinses and repeats as it can, but dies often. I can keep it alive with the gas pedal when circumstance allows. Car will stall on highway if i take my time shifting, neutral is dangerous. Also, gas pedal VERY unresponsive for first 15 - 20 seconds of truck start.
