Ok well i just finished installing a AEM SRI, Megan Header, and a custom 2.25 catback exhaust on my Ej8. Yeah yeah i know waste of money but it was all FREE. anyways after the installation my cars idle sometimes drops out of nowhere. Kind of like it wants to die and sometime shakes a little. Can anyone give me some pointers on why?

 

did you reset your ecu?

 

YUP! Thats what i dont get. I mean my cluster tach drops but my aftermarket tach doesnt really? Which is funny but you can certainly feel the shaking. Also i just changed the O ring to the dizzy. Maybe my timing moved slightly?
