Question about 1985 Plymouth Colt

Open Question

1985 Plymouth Colt stalls when hot.

My 85 Colt starts fine when cold. After warming up it begins idling rough and will stall. Hard starting when warm. To get it to start after it gets hot I press the accelorator all the way to the floor and crank away until it sputters and spits to a start. Almost like it's flooded.

Engine light could be from the spitting and sputtering, sounds to me like maybe bad spark plug wires, possible an ecm issue, what kinda code is it giving you when the engine light comes on?

SOURCE: colt idle problem.

Most likely you have a bad Idle motor which is a small motor mounted on the intake manifold. If the motor can run better with your foot on the gas but dies if removed then it is probably this. This motor is controlled by the OBDII computer which gets it's control signal from the temp sensor which is located either on the radiator or engine block (which could also be bad), if the electric fan (if equipped) turns on then this is not the problem part, but the idle motor is. Another possibility is that you have some bad /cracked vacuum hoses which should be checked for first, before replacing the idle motor.

SOURCE: 1991 Plymouth Acclaim stalls

One of the more common problems with the 2.5L & 2.2L engines that suffered the symptoms your describing, such as, starts & runs good, then at any given time would just quit, not start, but after sitting a while, or by the time the mechanic gets to it, it starts right up, or you sit on the side of the road for 20 min. or half hour then away it goes for a while longer, then quits again down the road. There is a pick-up plate under the distributor cap & rotor, with the wiring plug coming from it. 90% of the time, it's defective, and cuts out especially, but not limited to, more often when weather is hot.

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).

Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

High low idle, rough idle stalling


If it's surging, make sure your radiator is full. Do a tune up, plugs, wires, etc. Put some fuel injector cleaner in your fuel tank. On a cold start the vehicle compensates for being cold by adding fuel. Once it warms up the computer tells it to quit adding extra fuel. If it is a bad sensor of sorts, check engine light should come on.

I have a 1993 plymouth colt vista it runs stalls for the first 10 miles after you start it then it runs fine after that


it's possible your problem is with the warm-up regulator. it should be sending more fuel when engine temp is low to get itself warmed up, and then go back to regular fuel pressure at operating temp. maybe it's not sending enough fuel when cold.

Have a 1985 mazda rx7 will not idle .. cold start ok when choke is on once warm stalls and will not idle


There is a throtle adjuster right behind the carb. You can adjust it with a screw driver. If you are not sure where it is, just have someone press to gas pedal and you will see it move. RPM's at idle should be around 1,000 when it is idle once it has warmed up. Once that car warms up the choke moves back in and the car is probably stalling because it is not running enough RPM's.

4 cyl Engine starts and idles ok...give it throttle and it dies


I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?

Stalls when engne warms up


Your ECT (Engine Coolant Temp) sensor is bad. What's happening is at cold start it richens up the fuel mixture and as it warms up the ECM thinks it's still cold and essentially the "choke" is still on. Also check your coolant level. If you don't have enough coolant in you engine/radiator, the ECT doesn't know what to do so it thinks it's cold.

1991 dodge colt won't idle when engine is cold.


probably oil, it may be too thick when it's cold but once it warms up it liquefies and your engine runs smoothly. you could try changing oil, I'm guessing if you have a high performance oil the chances this is the problem may be greater since high performance things are usually geared towards working well when everything is hot
