i have a 2002 vti prosmatec, totally driven on petrol (no CNG at all,)
my car has a missing problem these days, it all started when i got irradium plugs in my car, i used those plugs for few days but then i changed those plugs and put the orignal plugs back, iv checked all coils, coils seems to work fine but
missing is still there
i'v got my car checked from few mechanics but no one is unable to diagnose the real problem
if you guys could maybe help me out
