Since few days my vitz is missing both on petrol and cng. I have shown it many mechanics some of them are saying that coils got bad this and that blah blah. However both coils and spark plugs are good as i have changed all of them. One of the mechanic told me that tappets/valves got jammed and the whole head need to be replaced from shair shah :s any idea guys what should i do??
u sure the coils are working fine?
and even if the tappets are jammed, can be fixed with machine.local terms"kharaad"
Contact Mr. Saleem 0300 2502066 i m sure he'll be able to help you out.
Check out the fuel pump.
I remember my Civic did the same, was missing a lot (on petrol), the fuel pump was gone.
