Question about 1987 Dodge Dakota

2 Answers

When I start the truck when cold the idle goes up to high mayby 2500 rpm. After it warm and touch the gas it runs normal but when put in gear it idles low and runs rough. It run pretty good for an 87 with 207k miles, but when you come to a stop it idles so low it fells like it wants to cut off.

My 2.0 engine idles fast on a cold start. Then idles down after warming up.


This is normally the way it is suppose to work. You need to have the RPM measured for High RPM and duration. What you are describing is how an electronic choke is suppose to work.

The errors would be how high the RPM goes and for how long it lasts. When cold the RPM, fuel mix and timing are changed to give a rich fuel mix. As the O2 sensors warm(Could be defective) they signal the engine to lean up. The water thermostat also has something to do changing the engine to a lean running slow condition.

If obtaining heat from your heater seems to take Forever, the thermostat could be weak. This would coincide with the engine continuing at a high RPM longer because it is not warming up.

I am not familiar with this car model but i would presume that the engine is linked with an automatic choke for cold starting and the revs should go down as the engine starts to heats up. this probably works on a vacuum system based around your inlet manifold, and the noise your hear could be a leak in the vacuum pipe. you should pop your hood before starting and try listening for that noise to pin point it's location. if your lucky you might just find a small crack in a pipe that can be replaced with ease. of coarse first thing in the morning would be the best time to check this when the engine is cold.it's worth giving it a go and i hope you get it sorted,good luck

89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed


This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--

Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.

Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.

You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.

These can be if the vehicle has them cleaned using a special zero residue spray cleaner.

First have it scanned to see what if any errors it shows--the computer.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

Buy a bottle of Techron Fuel injector cleaner. It's sold in many grocery stores and all auto parts stores. Pour the whole bottle into the gas tank when you can fill up. Drive the car and don't put more gas in until the car is almost empty. That should fix it

Idle flare is normal on all newer fuel injected cars. I think maybe you got a little paranoid,probably first spark plug change done by you. Gas milelage is easily explained in 2 ways, one the gov't is making the gas companies put oxygenated fuel into the gas & 2 you could go with a set of bosch oxygen sensors,pick up 15% more gas mileage

High idle at starting


Sounds like you have a vacuum leak in the air intake side. Check all your small and large hoses around the throttle body. Also check your idle air valve....cylindrical device connected to the the air box at the front of the engine.
