If I remember right there is a technical service bulletin about water getting into the ecm. If I am right he may find the computer either full of water or if you live in a climate that has freezing weather, the case may even be cracked. In the past we have been able to perform the recommended repair according to the tsb sucessfully, in some cases had to replace the ecm. Unfortunatley this question was moved from the Old FAQ, and pertinent information is now missing. This particular answer related to a particular car that is no longer mentioned.AnswerYour o2 sensor may be bad. AnswerOr your EGR valve/sensor.
If its a EFI motor it is more then likely dirty fuel injectors, they just can't get enough fuel through them when its cold. Compare it to a older carby car that didn't have enough choke..
Usually the computer will not look at the O2 sensor when the motor is cold.
The computer turns the AC clutch off when accelerating for maximum engine power. The AC compressor uses up some engine horse power.
all engines hesitate when cold they need to get to proper running temp
Most likely needs a tuneup done. Check the timing and change the normal tuneup part.
It was a coil pack.
No, it does not loose power but when the engine is cold, it is just harder to turn over.
Check for loose or worn serpentine or drive belts.
Sounds like a loose or worn belt, alternator or fan tends to do that when they get worn or loose.
could be where your power steering fluid is cold and thick
Yes, it does have an effect, but the real problem is the starter trying to turn over a very cold engine. The oil is thick and it takes much more power to turn the cold engine over.
With the engine cold, remove the cap on the power steering pump. Inside the cap is a dipstick with a marking for both the cold and hot fluid levels
Bad plugs and or wires.
rev hard and increase engine pressure.
in cold weather , engine may be so cold in the morning....
it might be your battery it so cold that it doesn't have the power to turn your engine over. i pull mine in the garage so it doesn't get as cold
Sounds like it is low on freon. Probably has a leak.
Signs of a worn timing chain are difficulty starting in cold weather with backfire and sudden brief loss of power while accelerating or decelerating ("stumbling").
slipping alternator/power steering/ auxillary drive belt
Yes it should.
The engine works more efficiantly as the air is denser when cold, more fuel can be used allowing for more power from a smaller engine
What have you done so far? Have you checked the brake fluid level?
Brakes dragging? Return ports on master cylinder restricted? As brake fluid heats it expands, if fluid return passages are plugged calipers will expand causing brakes to apply
Means to start the engine while it is cold (And has not been running for a few hours so the engine has gone cold)
Have had the same problem in the mornings or when the engine is cold. I suspect the power steering belt is slipping.
because the engine is cold and you need to keep the engine warm.
How cold is it. Most diesel engine do not responed properly when the engine and fuel is cold.
