Have a 1991 Subaru Legacy that runs on gas and gasoline.  Recently when running on gasoline the car has a hesitation when accelerating, when on gas it is just fine.  Wondering if its  a fuel filter problem or what else it can be?  The gas side has its on filter. Thanks

Umm....gas isn't gasoline?

There is a separate tank under pressure in the trunk, gas prices are cheaper in Europe,

they have conversion kits.  You can run both , changing with a switch on dash.Channging from gas to gasoline on the fly. Separarte injectors for gas.

I changed the fuel, air filters, no luck. I will check status of engine light. Need to buy tool.

I disconnected spark plug wires one at a time, spark working.

Most likely low fuel pressure..

 

I'm assuming gas you mean LPG

yes LPG.   I will get a OBD2 tomorrow to check engine light, wondering if a ox sensor would pick up gas fumes as opposed to  LPG fumes.

Getting ahead of myself, I will get the engine check light reading.

PO133 wondering if that's the real problem. OX sensor.
