VS v6 dual fuel troubles

[VSscott]

now im suffering a major problem with what i think is the dual fuel gas. putting my foot down it stalls/kicks back and the car just shuts down. but when i start it up again it works. i cant go fast up hills and cant go 90km/h+

any ideas of what may be wrong would be appreciated.

I have the same problem every now and then. Might need new leads or spark plugs. Its worth taking it to a gas conversion place and get your gas air ratio checked out too. My gas guy i take it to doest charge for tunes if it’s his conversion might be a good idea to take it to the place that installed it.
Hope this helped.

If your cars been backfiring you may have damaged yout MAF sensor and your car won't start on petrol if it is. The only way your gas would be back firing if theirs an electrical problem. Check your coil packs
