i can smell fuel as if its puttin to much through the engine i was a little heavy footed here and there but my last scoob was no where near that thirsty....

 

try the flash code test....maybe have a dodgey oxygen sensor

 

flash test?

 

flash test....error code test. behind the steering wheel there is 2 black connectors what you need to do is have the ignition off connect the connectors up then turn ignition on so the red lights on dash are on. then what should happen is the check engine light will flash if it flashes steady with 1 secend intervals everything is good if not then you have problems im not sure how you read the codes but im sure if you post help needed then ya will get assistance hope that helps

 

Im lucky if i see 150mile to a tank!

 

i take it yours is modified a bit?
