There are several things which can be wrong. Your car has a "cold start routine" which is similar to the old style choke. It uses a temperature sensor to trigger the effect. Most likely the sensor is failing to cue the routine.

On some cars there are 2 sensors with 1 operating the temperature gauge and the second operating the engine controls. You want to change the sensor for the engine control.

Another few possibilities are the ISC (idle speed control) which is a solenoid resting horizontally in the intake manifold. They can soot up and cause idle problems until they free up. And the EGR could be dirty and need flowing exhaust to free itself.

Last, but not least are your O2 sensors. They have heaters built in them to rapidly restore your idle to a lean condition. They should set a problem Code but a lot depends on the total of other factors that determine driveability. Their performance could be off but still within working range.

Finally, some engines have a part called a manifold runner. They can stick. IF your engine has this part this is another possibility.

Last, a small Vacuum leak. When cold metal heats up small Intake gasket leaks can reseal. Spraying a water mist from a spray bottle will make an engines' RPM change or stall. Just wet the seams of the intake manifold while it runs.

Please rate my info.

Locate you computer (right front kick panel) and tap on it with a pen while the car idles... Also flex it back and forth with your hands to see if the car runs rough or quits... You may need a new one.

this is a old model and it should have a cold start valve or it should have a coolant temp sensor, replace the colant temp sensor which is usualy located on the thermostat housing or on the intake manifold and this will sove the clod start problema!!

Have you changed your engine oil to a thicker grade for cold weather? Try 20/50 engine oil.

First you need to find the source that is causing noise. On cold weather is very normal engine belts or belts idle pulley bearings or belt tension-er to make noise, especially when they are old. Also power steering pump too especially if the oil is very old.

My Toyota Highlander will not start when the weather is cold, mostly in the mornings, but it starts easily, when the weather goes hot in the afternoon. HELP


Hi, Has a code reader been connected to check for trouble codes stored in the PCM? This would be the first step and the easiest procedure to do before guessing on a cause. From there we would know where to start a diagnosis.

2003 Ford Expedition Will not engage in drive right away. You put the truck in drive and give it gas it just revs up the engine then after a few seconds will **** into drive. Also is doing this at stop...


It sounds like you need transmission fluid and filter change. This is one of the most overlooked maintenance items. It should be changed every 50k (30k if you tow a trailer) The delay in engaging gear is sign that trans fluid is tired or REALLY cold. In cold weather this is a normal symptom on cold morning starts but goes away when warm. I'd get it changed and soon, before it turns into a $$$ repair.

White smoke, water vapor at initial start-up. drives a few miles, smokes again. could it be a vacuum regulator? 2001 jaguar s-type


Water vapor coming out of the exhaust at initial start-up is normal; that is condensation that collects when the engine is not running. White smoke at start-up depends on a couple of things. Tell me, where do you live? When the weather is very cold, all engines will emit steam (white smoke) when they are first running; this stops after the engine has been running a while and is warm.

In short, if this is only happening at first start of the morning and goes away over time, there is nothing wrong.

If, however, the "white smoke" continues and never stops, you may have a blown head gasket.
