I could be the cooling fans running constantly. My 2001 L200 is doning the same thing, I'm still trying to find out why both Cooling fans run when the engin starts. It started a few days ago, It was so loud I thought it was a car ahead of me with it's horn stuck on.
Acceleration Cable broken broken, you dump!
Adjust the idle screw.
zyou tps might be bad
On my Chevy truck it idles high when its low on antifreeze but if its not that more than likely its usually a vacuum line loose or cracked. good luck.
If the engine idles and revs up okay in neutral, it is likely the torque converter clutch lock up solenoid.
why does my 4.75 BRIGGS & STRATTON lawnmower engine idles high and low when cutting my grass
Need a little more info. What Model and year of the vehicle?
Needs a Tune up
the power steering applys load on the engine , specialy when making turns . if your engine idles low for any reason ( idle air control motor - bad or cloged egr valve - vacum leak etc ) then the car will die or try to every time you make a turn.
I have a 2010 and it does the same thing, only owned it for 3 weeks! I'm taking it back to the dealership
Year, make and model would help.
Run a compression test to verify the condition of the engine.
