Try to change LPG Supplier, maybe the LPG quality is poor or LPG is dirty.
Check the Oxigen sensors.

Hey,
Ive got a 30l-7a that sputters when the foot throttle is depressed for a couple seconds then picks up like no issue. Im getting no codes, misfire reports, or anything other than the sputter. Ive changed the coils, cleaned and gapped the plugs to spec, and changed the coil wires. Im out of ideas whats your take on the matter? thanks!
