| Symptom | Top-Level Cause | Solution | |---------|----------------|----------| | Engine stalls on switch to LPG | Liquid pressure drop >2 bar during injection | Replace LPG filter; check tank pump flow rate | | Poor cold start on LPG | Vaporizer top cover diaphragm stiff | Replace diaphragm kit (PN VIL-TOP-DIA) | | Rough idle, backfire | Injector rail top O-rings leaking | Replace injector seals (liquid-rated green FKM) | | ECU comms error | Corrosion on top of ECU connector | Clean with contact spray, seal with dielectric grease |
The liquid injection method inherently prevents backfire damage common in vapor systems. Environmental Impact: Notable reductions in NOxcap N cap O sub x , CO2cap C cap O sub 2
: Supports simultaneous, semi-sequential, or fully sequential injection, mirroring the original vehicle strategy. : The manual highlights reduced emissions of cap C cap O sub 2 cap N cap O sub x , and particulates compared to standard petrol use.
