SOURCE: Cold Start Idle Issue

Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

Inlet air temperature sensor, also known as throttle body temperature sensor, will do that. Don't go changing TPS, or IAC, as suggested in other post. If they work good in warm weather, they should do the same in cold. Air inlet sensor tells system how much fuel to deliver according to temperature, as engine needs more fuel the colder it is when starting.

SOURCE: Starts fine, Idles fine, Drives Fine for a while

you might want to chk. the crank sensor and or cam sensor. sounds more to me that it could be fuel problem. chk. fuel pressure. pump could be on its way out. don't be fooled by hearing the pump running as they sound like they are pumping but there not, at least not enought pressure to keep it running. pressure should be around 50 p.s.i.

SOURCE: Starts fine when cold, after running dies on idle then wont start

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.

Motor starts fine runs for five minutes then dies starts back up back up fine but no throttle response after thatfine.


if there is electronic throttle then probably needs replacement, get second hand one , or otherwise can try to take it out and clean it, if there is an access to electronic part of it try it open carefully and clean contacts with some alcohol, sometimes it helps

88 isuzu 4x4 Truck 2.6L. Starts then dies in 2 sec on cold start.


I would try cleaning the throttle valve body and also the automatic idle speed control valve mounted to the throttle body, this is a common symptom of a dirty throttle valve and idle speed control valve. Use a product called "CRC" Throttle valve cleaner, run the engine and spray it into the air intake of the engine with the supply hose removed, hold the throttle up while you do this as it will try to stall, use up about half the can and then shut it down and disconnect the battery NEGATIVE cable for 5 min's to reset the system learned strategy, drive it for a few days and see if this corrects the problem.

My car will start and idle fine sometime and sometime it dies and dies when put in gear


Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

My 98 Honda Accord Vtec 4cyl. eng is starting fine, but after start the idle dips a few times and regains for approx. 3min. If I drive without warming up the car will hesitate and the gas pedal will delay...


Seems like the coolant temperature sensor is giving the computer erroneous readings, and it is not adjusting the fuel mixture properly for cold engine operations. You should have the check engine light on, indicating this malfunction. The idle fluctuations are normal. The engine is trying to die, from the improper cold mixture, and the computer (ECM), recognizing low idle speed, is sending it back up. Another possibilty is that the butterfly on the throttle body is not closing completely, to allow richer mixture needed for cold starts.

Truck will start fine but if i drive it to say


Sounds like a problem with the idle air control valve on the throttle or an air leak into the inlet manifold. When the engine is cold the temperature sensor informs the ECM that the engine needs a richer mix to get started and to keep running. Once the engine is warmed up and the coolant sensor informs the ECM of that fact, then the fuel/air mix s set to the normal leaner balance. When you stop the hot engine and restart it the ECM is still seeing a hot engine and the idling is now very dependent on the idle air control valve for maintaining a sufficient running mix. If there is an air leak into the air ducting or inlet manifold the hot air under the hood will sucked in first. The ECM cannot sense this un-metered hot air and so the fuel mix is tool lean to fire. If it is the IAC there is an additional diagnostic to confirm if it is at fault. When the engine is running and the truck is stationary do you notice that when you turn the steering wheel (engage the power steering) that the engine badly falters and drops in revs for a second or two. If this is the case it looks like IAC valve is not functioning properly. To fix: 1) remove the air ducting from the front of the throttle and clean the throttle interior and plate until like new. 2) locate the IAC, its often on the throttle body and is a small device held on with a couple of bolts with an electrical connection to it. 3) Disconnect and unbolt and again clean thoroughly Check the two ports on the throttle body exposed by the removal of the IAC and clean these. Reassemble and it should work OK

Saab 9-5 need to give alittle throttle for cold engine start


the idle air control valve may be bad or just needs cleaned out. idle air control valve acts the same as a choke. if it is messing up it will cause engine not to run right.
