i have an 06 IX MR. the problem i have been having is when i idle, weither its with the clutch or in neutral, my RPMs drop down to about 300rpms and acts like it is about to shut off. well yesterday it finally shut off and i was just wondering if yall new anything about this situation... thanks guys...

 

More info.....mods? changes you made recently? has this always happend since owning the car?...

 

Thats the question.

If your stock, and have had no ECUflash, you should have no idle problem.

 

im sry guys... i have full turbo back exhaust including manifold,intake,bov,interooler,piping, GT30R with dump pipe, and just a tune. its right at 410whp.. it has been doin i guess since i got that new turbo.. it has just been getting worse and worse and now it is finally shutting off. if yall need anymore information please let me know.. thanks

 

Did you have the intake and bov prior to the new turbo? Are you on the stock ecu? is the bov diverting back into the intake or venting to atmosphere?

 

if you could log your car while idling that will help people solve your issue as well. make sure you log your fuel trims as well.

 

sounds like the bov is causing it...seen this problem way too many times with ppl using aftermarket bovs that arent recirculated

 

Check your vaccum lines, also make sure your DV or BOV is in there pretty good, kind of sounds like the issue I had when I forgot to tighten my DV and it popped out... Are you still running MAF?

 

Check BOV, all piping, vacuum lines. You could try the idle screw on the back of the intake manifold, until you find the issue.

 

Does it drive rougher?
I think its a vacuum line that came off maybe two. Check the ones behind the throttle body EGR ones.

 

After you check all those darn vacuum lines....Since you are modded you might consider an idle screw adjustment. (BIS). There is a hole on the rear of the throttle body. Insert a screwdriver and carefully turn up the idle.
