hi guys:
when i start the car rpm rises and fall between 1 to line above zero. engine sometimes stops ,some time keep running at very low rpm and keep shivering.
Different mechanics have checked my car, they set the rpm, fix at 1, but after a day or two the previous condition returns and rpm gets low just above line above zero.
due to this problem my car's engine even get stops middle on the road.
problem is not on petrol car is perfect...
ive tried
oil and filter change
cng is off for six months
i have been running this car on petrol .
one mechanic told me that carb has to be cleaned.
but even when mechanic sets the rpm to one through some screws, why rpm get low to zero after some days?
need help
