alright last tuesday i installed a coupe middy on my sedan and i have noticed since the install that when i stop at a light or with the car on P it idles way too low, it even sounds like is gonna stall, it has the kind of sound like when it needs new plugs but i just replaced them yesterday, it drops down to around 550rpms-600, it only does the stall thing when im at a light or something, not when the car is running, could it be a leak from the middy?? thats what im thinking but i wanted to ask bc i know theres a lot of knowledgable posters, thanx in advance

 

I'm willing to bet that it's an exhaust leak. Check all your connections.

 

thanx, anybody else??

 

check your gaskets and connections too
did u re-use ur old gaskets?

 

Wierd, I had sorta the same simptom when I installed my plenum spacer, ztube and K&N. It would idle way too low, and feel like it was about to stall. I followed the procedure for the "idle air volume reset" and it worked like a charm. Car consistantly went to 650 RPM at idle, even from a fast decelleration, or when revving it.

 

do you have a link for that reset??? thanx


:edit: nevermind, i think this is it https://g35driver.com/forums/faq-diy/6538-ecu-resets.html
