Dear Xulfiqar bro i ve brought khyber(Stock engine) last year and it was on petrol but ive installed CNG in it but there is a problem now the car engine heats up quickly on cng but on petrol it remains below the half of temp gauge what could be the issue as ive flushed engine/ radiator completely and using guard red one coolant as its without Tstat Valve and auto fan and also changed water pump and belt.
and one another thing is that as ive brought the car and fixed most of the things myself, in one cylinder plug adapter was installed (near to distributor) and nut type thing was fixed in the middle cylinder so two plugs were far from combustion chamber, i ve removed both of them and installed new plugs nothing happened engine starting considerably improved engine was missing badly earlier, i was curious why someone would install that? engine is not eating oil
