When i start my vitz after a long rest i.e. after 7 8 hours the car doesnt accelerate on petrol immediately i.e. when i press the full accelerator car starts to shake no acceleration but when i leave the accelerator the car idle is quite normal this happens for first 5 10 minutes but after this car runs perfectly fine. Car is on CNG is it due to emulator setting or what??? Experts need ur help
Sir is the car running fine on CNG?
yeah on cng it runs lika e charm
probably the throtle body has a lot of carbon in it by now, causing rough/cold ideling
Or if u dont drive on petrol condtiions cud be worse, a dead fuel injector, low fuel presure from the fuel pump (a dirty fuel filter) etc.
+1do run few kms ur car on petrol before filling ur CNG.
