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!

In 1923, French tennis player René Lacoste was promised a crocodile leather suitcase by his captain if he won his next match. He lost the match but won the nickname "the crocodile" which he had sown onto his tennis attire. Ten years later he launched the first polo shirt and Lacoste, the first brand to feature a logo on its clothing.
