Today hi guys got a 96 vs on duel fuel, it backfired on me on gas and now i have no acceleration at all, on petrol or gas, it starts and idles but no throttle at all.its making a low popping noise from the air box, replaced air flow meter with a second hand one with no change ,checked air intake tube for cracks/splits but ok, dropped off the exhaust after the cadalitic converter and no change.checked the fault codes and nothings coming up accept 12 which is ok, its got me stuffed,anybody had a similar issue? or any ideas ?
Air filter okay? Might want to check the throttle body cable is still on, while you're there clean the throttle body in case it is stuck
