ean611 Posted December 25, 2011 Author Share Posted December 25, 2011 I have some misfires and rough idle. I've already addressed most other sources, I'm pretty sure it's the FMIC. Link to comment Share on other sites More sharing options...

bmx045 Posted December 25, 2011 Share Posted December 25, 2011 Go through every pipe high and low. Did you log? Whats your idle vac reading, a/f trims? I dont see why you need a lift, two couplers under the bumper which you can reach your hand to. Link to comment Share on other sites More sharing options...
2005hondakilla Posted December 25, 2011 Share Posted December 25, 2011 that sounds more like a tuning issue....maybe even a loose inlet. Link to comment Share on other sites More sharing options...

I dont see why you need a lift, two couplers under the bumper which you can reach your hand to. I the couplers at the bumber aren't easily accessable with the bumper cover on. Removing the bumper cover is much easier with a lift. I've already checked with the tuner and the tune. I've already fixed two leaks related to this, one at the drivers side IC coupler and the turbo inlet hose. Seeing as I'm seeing the same thing still, I suspect that another coupler may be leaking. As it is very cold, the piping may have developed a leak in the cold. Link to comment Share on other sites More sharing options...
bmx045 Posted December 25, 2011 Share Posted December 25, 2011 Get a ratcheting 10mm crescent and they can be tightened without removal of the bumper, what kit do you have Link to comment Share on other sites More sharing options...
ean611 Posted December 26, 2011 Author Share Posted December 26, 2011 RacerX V3. I've tried to get in there with what I have, and I don't have enough space. Every time the car is cold, I'm CEL'ing it up.... Link to comment Share on other sites More sharing options...
johnAWD Posted December 26, 2011 Share Posted December 26, 2011 What's the CEL? Link to comment Share on other sites More sharing options...
bmx045 Posted December 26, 2011 Share Posted December 26, 2011 Just an fyi intake manifold gaskets on 08's were pisspoor and caused cel misfires in cold start conditions. The rough idle subsides once engine is warmed. I have a writeup explanation in the walkthrough maintenance forum Link to comment Share on other sites More sharing options...

The rough idle subsides once engine is warmed. I have a writeup explanation in the walkthrough maintenance forum My intake manifold gasket was changed at 31xxx miles when I had a new shortblock. CELs are P0301-4, just misfire codes. It's consistent with a vac leak in the IC piping. Link to comment Share on other sites More sharing options...
20lgt06 Posted December 31, 2011 Share Posted December 31, 2011 throw on your stock on to test if it is your fmic Link to comment Share on other sites More sharing options...
ean611 Posted January 1, 2012 Author Share Posted January 1, 2012 Can't, not sure where all of stock IC is. Also, CELs have stopped since I tightened some of the clamps. Now I'm still getting a lightly rough idle, but I now have new couplers for all joints, and am going to replace a few and see if that helps.

ean611 Posted January 1, 2012 Author Share Posted January 1, 2012 Found a problem. Flange/turbo coupler has dent in it. No idea how that happened. Pmed itsme already about getting another one. Also one of the junctions looks like i should redo it, but it is between the engine block and the bumper, so need to dissasemble that ( bumper cover) to replace that. Bottom line, need another part. I tried to reseal things with clamps the best I could. May need to smoke test it later if I can find someone with that tool. After my mucking, idle is marginally better as I tried to seal to the part of the flange that was good. Link to comment Share on other sites More sharing options...
