you'll find its been tuned to gas, I would change all the TEEs in the water side of things to Ys stop
any cavitation ,plus its more efficient.
Make sure your leads are clean and plugs are the correct heat range.
99% of gas problems are 12v related,
it running like a dog on petrol as they dry up the seals from lack of use.
I had a duel fuel for 450K what apitb, but it was my choice.
ideally gas likes the timing a tad advanced as well just off pinging on petrol.
yell out if you need help elsewhere.
When you clean the Maf disconnect the battery so the ECU can re learn the new values
