before i got to bings meet last year at Sq1 i filled 1/2 a large NYF cup full of gas leaking from my filler neck/tank and pissed a steady stream 1/4 of the way to st.Catherine’s before it just started to drip every second and still got 2x more kms to my tank…120kms a tank jeez. fkd up

I have a new cat (1 month old), new O2 sensor (1 month old) and a brand new air filter. I just replaced the plugs with NGK Platinums and installed premium Bosch wires as well. I’m getting about 300km with 70% city and 30% highway. I believe the car is running rich because after I beat on it a bit, it starts to smell like rotten eggs, possibly indicating that the unburned fuel is going to the catalytic convertor.

I am pretty frustrated and don’t know what to do next. I bought a PCV valve, distributor cap & rotor, thermostat, fuel filter and water temperature sender…gonna get them installed by a mechanic very soon. What else could cause this fuel efficiency problem? I’ll try giving the MAF and Throttle body a cleaning too once I get the chance.

btw I’m running 5w30 on a stock KA24DE with an auto tranny and I use 91 octane most of the time from Sunoco…also I use winter injector cleaner with every fill up, bought from Crappy Tire.

Why the hell are you putting 91 octane into a ka24de.

yea thats all HORRIBLE Lol… when I drove my 97 back from NY when It was stock… I got Incredibly good gas milage. I got close to 700 kms for a tank of fuel… Mind you that was ALL hiway through penslveinya. going to detroit. I cant believe some people here are getting suck low fuel milage… WOW lol… And you actually pass emmisions? lol

My 98 eclipse gsx with 400 AWHP stil got good hiway milage… I would get like 500-550 a tank of 94. BUT when boosting all the time. the 880cc injectors didnt really care about fuel milage haha.
