Hi friend.
Do you think I have big issues...? But the reason for my request here, on this thread, is just that. What do you think, personally, that could be the issue? I did make a diagnosis here in Italy with a GM factory diagnostic port and not gone out of issues. Friday I'm going to do an "upgrade" to the controller, and then we'll see. But then again, what do you think?

 

I'd say have a dealer look at it.

I assume you aren't;
running with 13" tires
dragging a parachute behind you
rolling with a 30 foot satellite dish on the roof
running it like a two speed (full breaks or full throttle)

Do you have a locking fuel cap to prevent someones petty larceny and stealing small amounts of fuel at a time?

 

Man I dont know.. thats really really tough to diagnose over the internet. If there are no CEL's then I'd be worried. What rpm do you shift at? How quickly do you gain speed? What mods are done? Even when I had 2,000lbs of cargo and passenger, going thru mile long hills in west virginia, I didn't get below 14.5mpg going 76mph.. so you REALLY have something up. The dealer is your best bet. Seriously.

Ya this^^ Even then I wouldn't expect that kinda mileage lol.


Aww crap. I'm thinking of an H3 here; not a 2. But still, your 2 should be around 10-12mpg. I'd clean the injectors with some seafoam or proffesionally, air up the tires, make sure the filter is clean, and adjust driving style. I cant believe I didnt realize I was in the h2 forum not h3. Sorry

 

I put street tire on this weekend and went over Hwy 2 again, this time got 16.5. Tires inflated to 40psi. (Yokohoma Geolanders)
