i am facing a problem which i have been unable to diagnose.
The problem is a "Hichki" (some time one and sometime in pair) which occurs under no specific condition like RPM, load, gear etc.
I have done the following DIYs tappet (inlet 0.006'', outlet 0.008'' at cold engine), plug gap 0.80mm, distributor signal generator air gap 0.008", swapped the plug wires and distributor with other ones, adjusted the CNG mixture but nothing, the hitchki can occur at any time and is gone with out any trace.
It feels like the car engine is turned off for a sec and then comes to life again.
I am planning to visit pindi/islamabad at the weekend and am concerned about this issue, as this may get me in to trouble on the motorway.
plz guys help me out here
