    Hey everyone, So I've noticed my gas mileage is extremely poor lately. Well I guess I didn't realize it was poor until I started calculating my Odometer between fill ups. I have a 08 and get roughly 15 MPG. Usually between 240-260 Mike's before hitting empty. Car isn't showing codes for fuel...
  2. 2006-2012 Eclipse (General 4G)
    I've been running into an issue where my Eclipse intermittently won't start. The engine cranks fine but won't start. I had it towed to a repair shop but after it sat for 2 days before they looked at it, it started fine. The checked for codes, tested the fuel and tested fuel pressure with...

    So I've been recently having issues with my 2006 mitsubishi eclipse 4 cylinder car. It happened out of nowhere that I started getting a rough idle. Which showed up as a misfire on cylinder 2 when I plugged in my obd2 reader. I've tried fuel injector cleaner. Higher grade gasoline, replacing the...

    Do we have fuel filters that need cleaning or replacement?
  5. 4G Eclipse GS/SE Specific
    I just patched the two vapor return lines that seem to rust out under that heavy steel cover. ( got the p0442 and then the p0445 ) . I see you can order the entire filler tube component, is it hard to replace if I put the car up on ramps ? Can you get to the upper filler neck hose connections...

    So in my area premium is 93 octane, mid grade is 89. What do you guys think about mixing 93 and 89 octane in order to reach 91 octane.

  8. 2006-2012 Eclipse (General 4G)
    Okay so I just purchased a 2006 Mitsubishi Eclipse GT Automatic Transmission with 70k miles and great condition: due to reliability, I love Mitsubishis, and the car is atheistically pleasing. My question is, is Premium Fuel REQUIRED, will mid-grade be a fine alternative, as it is only slightly...

    I have been looking around and it seems that RRM makes turbo kits for the 2000s lancer ralliart that shares the same engine, 4g69, with us. They also make performance parts for the 4g69, like port and polished intake manifold, and turbo exhaust manifolds, that in the site, they say it fits the...

  16. Problem Reports
    I've got something going on with my Eclipse 4G, and I can't figure out what it is. I'm trying to avoid taking it to a shop and blowing 500% more money than what the repair is worth on mechanics time and repairing parts that aren't the problem. So I thought I'd ask here first. Here's the deal...
  17. 2006-2012 Eclipse (General 4G)
    2009 Eclipse GS. I was talking with my co worker about my fuel economy or lack of. He suggested changing the fuel injectors. Will this increase my fuel economy and if so could you steer me towards what products to look for. I would have a mechanic handle this job. Thanks
  18. Eclipse Performance
    Hi everyone, I've creeped these forums for a couple of years since getting my Eclipse for ideas on what's working for others and what I should avoid. About a year ago I saw both the AWD Eclipse that's been created and a video on a Civic Type-R with in-hub electric motors on the rear wheels to...
