Depending on the make model and year, could be a problem with the idle air control valve, a vac leak, or dirty throttle body.

SOURCE: 98 Isuzu Trooper stalls on cold start, idle issues..

I had the same issue on my 99 Trooper.

It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.

I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.

They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.

Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor

The total cost to me was $345.00, and I definately don't feel gipped.

SOURCE: COLD START ROUGH IDLE

I hate to be the barer of bad news, but may be the head gasket.

My car started with rough idle. Then very hard to start in cold weather. Next started overheating, but no output from heater. Trickling sound from behind dash board. Overflow bottle overflowing.......

I replaced the water pump, radiator cap, thermostat, coolant, fan belts, power flushed the system. Nothing worked. Some research gave me the answer.

The head gasket leak was allowing exhaust gases to enter the cooling system, displacing the coolant. After use, as engine cools, coolant is sucked back into the system and coolant seeps into the cylinder. This gets worse over time.

First thing you'll notice is the rough idle as the spark plug burns off the coolant in the cylinder. (This is especially true at low temperatures.) If it is the head gasket, the other symptoms will follow as time goes by.

Stalls after start up, Stalls when braking, then runs fine after a few minutes


Check the ECU engine temperature sensor. If it thinks the engine is hot, it will struggle to run when cold.

I have a 2006 dodge magnum 2.7 with 136k miles, I changed the coil pack, spark plugs & a new throttle body all OEM parts... Once the car warms up my idle drops to 625-700 but it feels like it wants to...


Hi Gabro
try this procedure and let me know if it work.make sure the engine is in normal temperature, all accessories are off.
start the engine and let it idle for 1 minute.
put the selector into D and let the engine idle for 30 seconds.
turn the AC on and let the engine idle for 30 seconds.
turn the AC off and let the engine idle for 30 seconds.
put the selector into P and let the engine idle for 30 seconds.
switch engine OFF for 2 minutes.

Starts and stalls, abs, odometer & speedometer out


Check for coolant temp sensor fault, It will affect cold start and idle. It controls open loop mode in the ECU (cold, high idle, open loop) Perform an OBDII scan of the stored fault history. Also make sure coolant level is correct.

1996 mercedes c280 dies when put in drive


Engine stalls 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

When starting car the rpms jump up to 2000 then jump down to 500 while feeling like the engine is going to stall out then the rpms go to a normal idle but idles rough for about 5 seconds


its becouse the cars computer tries to heat its self for it not to work when it is too cold
so just leave it there for a while till the rpm go to normal

2007 crown vic 4.6 l idles high on startup


This sounds like a normal condition.What happens is the cold start emission reduction component monitor(software program in the computer) is running.
Cold Start Emission Reduction Component Monitor
The Cold Start Emission Reduction Component Monitor was introduced for the 2006 MY on vehicles that meet the
LEV-II emission standards. The monitor works by validating the operation of the components of the system
required to achieve the cold start emission reduction strategy, namely retarded spark timing and elevated idle
airflow.
When the CSER strategy is enabled, the idle air control system will request a higher idle rpm, elevating engine
airflow. While this CSER elevated airflow is requested, the low airflow test compares the measured idle airflow from
the MAF sensor to the commanded idle airflow from the idle air control strategy.
