I have a city 2004 on cng. car was previously maintained by my father, however, this time i need to get it done myself.
I have been observing the following things:
1) Slightly higher fuel consumption
2) Lots of oil in the head and Cylinder.
3) car hesitates a little when i give race in 1st or second gear to gain speed. after that it becomes fine.
I was thinking it was asking for a tunning. Last time it was tuned 16 months ago. Can some one tell me what i should do/have done for good tunning?
I was thinking, getting the throttle body cleaned, changing plugs, getting the cng kit cleaned.
Please let me know if i should do anything else as well.
