Yesterday, I stuck for 2 hours in bad traffic jam near National stadium due to match & during this, my Khyber got little overheated & started severe jerking, power loss, engine stalling, Rpm fluctuations & finally shut off. I tried to start but it was not starting, neighter it was converting to cng.
I called mechanic, he came & changed all spark plugs with new plug coil & distributor coil. It started perfectly.
Today in afternoon, similar situation and during 2 hours stucking, car again repeated same symptoms & switched off. I left it off for 15 minutes & after cooling rest, I started & drove perfectly without any issue.
Today in night, when I was returning home, same symptoms came again & this time with severe burning smell and smoke. Suddenly car switched Off in 4th gear. When I opened bonnet, I saw cng/petrol cut-off switch/valve burning in smoke along with its wire connections & associated horn clips.Also petrol pipe attached to it was also burnt /damaged little so I disconnected battery terminals immediately to control burning/fire extent.
Now please guide me what to do now. Which parts to be checked? Note that all the time A/c was ON & I observed distributor little hotter
