Poor idling when cold/Rpm unstable
The problem started when I found a coolant hose craked and changed it, it doesn't make any sense right?
I first start the car, The RPM goes from 1,400 to 800 or 600 and jumps back and forth, sometimes the car shuts off.
You need to give the car too much throttle to make it go.
This happens when the car it's cold an when it get's warm the problem almost dissapears.
I cleaned the throttle body, EGR valve, Air filter, checked the gas tank and the fuel pump and the problem stills.
I've already changed spark plugs, cables, coils, MAF sensor and nothing
The check engine light doesn't come on and the car doesn't throws any codes.
It's driving me crazy!
Is dit een goede vraag?
