    Im thinking about gutting my cats, since rre doesnt make their headers anymore, i could order rpw headers but since they are from australia, shipping costs might be absurd. My one question before gutting my cats is if it will pass emissions tests, i will only gut the precats, put spacers on the...
  2. Problem Reports
    I have a 2009 with the 2.4L that after pulling into the driveway the other night the check engine light came on and it started idling rough as hell. I shut it off and restarted it. It started back up but ran rough as hell, tach was at around 1000rpms but it felt like 150-200, it would finally...

    Hi all! I'm looking at options to fix a CEL cat code being thrown (the CEL has come on and off several times and the first time I got the code read but don't remember it exactly, only that it was a cat converter one). I've read here that RRE exhaust headers can be used to bypass 2 of the 3...

    Hey everyone! My son's 06 Eclipse 2.4L died last night on the highway. His CEL gave the codes of P0421 & P0431 as well as P0102. I understand that the codes mean that the cats are bad but the P0102 was for the MAF. The car will start up but will die immediately without feathering the gas...

    I wrote this up as it has been a common question throughout the years. Commonly people install cheap aftermarket headers and experience a number of codes from the misfire P0300-P0301,P0302,P0303, P0304. Also, system too rich/too lean. P0171,P0172, P0174,P0175 etc. Although this is correctable by...

    As the title suggests, I've recently discovered that the Quaife LSD for our GTs has been discontinued. ACI no longer carries it, and it is no longer listed on RRE's site. THM had to cancel my order because (I assume) they did not have the LSD in stock and issued a refund. Sent an email out to...

    (If this review doesn't belong here, I apologize.) Stayer Tune Review. After reading many reviews and also reading Stayer's numerous posts, I have decided to go for his tune. Most of the reviews that are already on the forum are very well written, so my review wouldn't be so different. The...

    Just a quick question, i've looked around 10 or 15 minutes, haven't found much of an answer but, if i threw CEL or SES, could i use a scangauge 3 to clear it? And is the ScanGauge 3 any good, just for monitoring gauges and clearing codes?

    Lord Jesus help me! The rear cat is impossible. At the very least how would i access the the downstream o2 sensor on that cat so I can add spacer to turn off my CEL.

    I feel like my engine chatters a little bit at idle. Is this for all G4s? I hate it and feel a little embarrassed going thru the drive thru at places. also idle can feel finicky at start up. 40K miles no CEL.

    My Ebay CAI i modified and car running perfect :) So as a few of you might know, when i got that Ebay CAI my car did not idle correctly and my CEL came on. All because of the Ebay CAI being 3" all the way through like alot of you have described being the main problem. The high end CAI's drop...

    Hello, everyone I have a 2007 Mitsubishi Galant Ralliart and I'm looking to buy headers. I've been riding with the CEL on for months due to O2 sensor in the rear, I did the spark plug fouler mod and it worked for about a week before the CEL came back on. My city MPG has decreased and I've...

    Morning. Just wanted to say this website is great. Good info on here if you search for it. Not new to the car scene, new to the Eclipse scene tho. Traded a Grand Cherokee for a 2006 GS with 90K miles on it. I love this car. Espcially since the MPG is much better than my Jeep was. Since getting...

    Hey there, I have just recently joined and have had a problem going on for about a month and a half. My RPMS tend to drop and pick back up at idle( or at a stop) but goes away and comes back after driving around for a bit. My CEL goes on but turns off before i can get to a shop so they can check...

    Installed RRE headers awhile ago. CEL came on immediately and I ended up boring out the spacers for the 02 sensors which made the light go away...for about 8 months. Light came back a few months ago and no matter what I do or how many times I reset the codes, CEL continues to pop up about 12...
