A/C On Rocking Idle?
A/C On Rocking Idle?
When my AC is on my idle wil flucuate between 400-1100rpm constantly and never be constant. It does it very harshly. If you turn the AC off, it clears up and idles fine. Any ideas?
I recently put on a new aftermarket new intake, but it was just replacing an old aftermarket one. Which I only changed because I had no clue who the manufactor of the old intake was.

This is most likely causing your problems. I had intakes on my 2008 and 2011 and never had issues, but apparently a lot of guys do. I guess it just depends on the location and sensitivity of the mass air sensor.

Same here..
With the AC on, rpms bounce and the AFR hits 17 & smtimes --- and the car goes off
Without the AC on, AFR is usually normal but somtimes goes to 13's and 17's bouncing the rpms frm 500-1000 getting back to normal and repeat in a circle
Air mass sensor was recently replaced by the dealer with a new one
mods I have are ETS INTAKE, ETS IC KIT, ETS FULL 3" EXHAUST, EBCS BOOST CONTROLLER,
Just fr the info, ive got STOCK BOV, STOCK FUEL PUMP, STOCK INJECTORS

If you are running an aftermarket intake without a full on heat shield, your idle will jump around when you turn your A/C on cause the fan will blow hot air directly into your filter causing the rough idle...
I had this exact issue until I ordered the MAPerformance intake shield, retrofitted it to my COBB intake and sure enough, problem solved after that!
