I have Suzuki Mehran that has been tuned up on CNG on by mechanic about a week ago and the air filter has been changed. I even had the CNG kit cleaned by the CNG installer about month ago. Now the trouble is that the car is missing (very light) on unspecified interval on idle sitting. The car accelerates fine, with no trouble. I feel the car missing (very light) also when I am coasting ( the car is in gear, accelerator not pressed and the clutch is not pressed).
Yesterday at the shopping mall, when I came back to start the car. The car would start, but the it would shut off immodestly. This happened 5 times. On the sixth time I waited for 30 seconds. Then the car started on full accelater pressed. The little missing is still felt, and I believe when it misses the temperature gauge goes up a notch.
What could be the problem? I have shown it to two mechanics and they say its fine. I think it could be some electrical problem. What do you say?
BTW I am Karachi, So any go mechanic near Ayesha Manzil for diagnosie would be helpful, or a DIY would be a better option for me.
Thanks in advance ya all!
