  1. 4G Eclipse GS/SE Specific
    Title is pretty self explanatory, but I just installed a GT Throttle Body I picked off a scrapped V6. After installing however, I threw code P0174. I’m assuming this isn’t usual for most people, so I was wondering if anyone could help me pinpoint the issue. Everything was installed as shown...

    Hi I’m new here but I have an 06 eclipse gt 6 spd 46k miles. The p0037 code is tripping the ses light ... I just added an injen CAI and was wanting to start tuning the car ..no one around SE Missouri has anything on tuning anything except LS motors. So...what can I do here? Does fastworks have a...

    Hi everyone, hope you all are doing well. So my 07 GT (6-speed) is experiencing two misfire codes. At first, it was P0304, so I checked the front bank of spark plugs and found the plugs and boots to be covered in oil. I changed the valve cover gasket and tube seals on those, and the code went...

    Hello everyone, I own a 2007 Mitsubishi Eclipse GT and I've had the dreaded O2 sensor codes for as long as I can remember. Just the past weekend, I decided to gut out my pre-cats and install O2 spacers for the oxygen sensors (All 4). I was hoping that the codes would finally disappear but sadly...
  5. Problem Reports
    I have a 2007 Eclipse GT. For a while now I've been having my SES light on because of an O2 sensor problem (P0037 Bank 1, Sensor 2), which I've checked is a pretty common problem with the eclipse. I've replaced that O2 sensor a few weeks ago and deleted the code. It came back after driving a...
  6. 4G Eclipse GT/SE Specific
    I had the SES light come on while driving long distance, on a steep grade (P0157, P0137), then next day no light. I scanned and found the codes stored, not pending, then they went away completely in about 2 weeks. The same scenario happened again, but this time the codes aren't clearing. Any...
  7. 2006-2012 Eclipse (General 4G)
    Ok so my car wouldnt turn on last week, and threw some codes. Cylinder 3 misfire and bad fuel injector. So I replaced all 4 fuel injectors, and those codes went away but now I had a new issue. Camshaft sensor was bad, i replaced that yesterday...it still wont turn on. When i try to start the...
  8. 4G Eclipse GS/SE Specific
    so at my work yesterday my Master Tech installed my headers and my magnaflow exhaust on my car. we even gutted the cat on the bottom by installing a 2.25" pipe and some band clamps. overall it sounds amazing, just now it has the idle issues along with the acceleration. thankfully I made it home...
  9. Problem Reports
    I've been browsing the forums for the code P0421 and it seems many people have this issue. I have read Desert Rat's post about this problem on the constantly asked questions but this is for when the SES light is on, and mine is gone. In addition to this, I have also recieved P0174 and P0171 but...
  10. 2006-2012 Eclipse (General 4G)
    I had my oil light come on apparently my car was leaking oil, took it to mits they tried telling me it wasnt a sensor it was either basically a blown engine or a lower engine issue. Which when i asked them what the problem was they should have stated oil around that sensor. Specially since the...

    I have an 07 GT Spyder with 122K miles. It's my DD and she still purrs like a tiger. I got these error codes last week while driving back from work. I read the codes after I got home, and hoping it was a 1 off I cleared the codes and the SES light stayed off for about a week. Now the codes are...
  12. Problem Reports
    Hi everybody, I've searched the forum for this specifically and I could not find anything on this, so I figured I'd post a question about it. Recently I've purchased an A/M Header w/integrated cats; replaced Bank 1 Sensor 1 O2 Sensor, and managed to reset all codes after logging necessary...
  13. Mid-Atlantic
    I am looking for place/someone with garage or setup to properly gut my header cats and install O2 sensor spacers. I have the dreaded warm-up cat failing code and I'm not wasting money on another one (once changed under recall). And I'd like to pick up some performance while looking stock for...

    Just bought a 2006 Eclipse with 105,000 miles. I got it for $5600. Did i pay to much for this vehicle? Also the damn SES light came on, took it to AutoZone and came back with P0421. It had 3 possible problems, so im hoping its just the O2 sensor. I also hope this isnt a sign as whats to come...
  15. 4G Eclipse GS/SE Specific
    Good Morning everyone. Last year I purchased a 2006 Eclipse. The SES light was on when I purchased it. I am pretty handy at rebuilding things so I figured I can find out what the light wants, fix it, then make the light go away. I am getting a P0603 Keep Alive Memory error. I have tried many...
  16. 4G Eclipse GS/SE Specific
    Hi all, I have 2012 GS, and this morning my service engine light came on. Took it to Auto Zone and they told me that it's a 404 code and sold me a new fuel cap that i supposedly needed since mine was lose. We just cleared the code by disconnecting the battery, but i won't know if SES light will...

    Hello all, new member so please go easy. OK I'll try and not make this long. I was doing 60mph on the freeway and the car just died (2006 gs manual). Turned out my timing belt and I think balance belt snapped. The mechanic sent the head out to be machined. He later reported back that I only...

  20. 2006-2012 Eclipse (General 4G)
    The jist of this post: If you live in Washington state, you can pass the emissions test while throwing the code P0431 (and presumably P0421). (My exhaust is stock with all 3 cats) The wordy version: My cars been throwing P0431 for the last year and I've been procrastinating taking it into the...
