Solved...
Aoa members and @Xufiqar i m facing serious problem ... cylinder misfire severlely at cold and reduce misfiring at hot ..misfire can b feeel throgh silencer phuk phuk phuk .. all 3 cylinder loose power on removing wires but cylinder 2 does not loose power specially at cold ... i checked wire spark is coming to cylinder 2 ... misfire happnd at petrol and cng ..i checked wire by exchanging cylinder wires(with correct firing order) cylinder 2 still misfires
i m considering following problem plz rectify them
1) valve stuck
2) ignition coil or rotor + cap
3) plugs (but plugs were cleaned and i dont know internal resistance would b ok or not)
@xulfiqar ur meaningful opinion is required
Update:
Most if Mechanuc suggested head work is required . I was indulge with disappointment n did valve clearance but it didnt solve problm so ..... wuth a last hope changed plugs with new one and problem was solved till now
Thanks to allah n all of u
