rough idle service??
I am probably going to take my car in to see if they can pin point the cause of my
rough idle. My question, should I put my stock air box back in or leave my sr intake in???? |

thats what I was thinking. I might do some testing tonight with stock box and see how that works.

Good luck with your rough idle. I've had the same problem for a while, It idles in normal range but when it goes around 750-800 it starts to shake a bunch.
So far they've changed front motor mounts, and replaced plugs, wires, and dist. I get much better gas mileage now, but still bad idle. |

put the Stock box back in. Idle improved a little, but still going to take it in. hope its an easy fix.

Be sure and let us know how it goes. It seems to be a common problem on the 8's.

My idle use to be smooth as ice until I had a PCM Flash 2 weeks ago.
Now my idle (while in gear / AT-stock) shakes the whole car. To me, it feels like the exhaust system is vibrating against the under-body or a motor mount is loose. If I increase the RPM from 750 to 1K, the vibration disappears. It does it in reverse or in drive. I've taken it back twice trying to resolve this nuisance, I suspect they parked it and never looked at anything on my 8. |
I've read of several folks getting motor mounts replaced (and finding that to improve their idle vibration). If your air intake didn't solve the problem I'd suggest pushing for a warranty motor-mount replacement.

Ive done a few motor mount replacements, make sure they do both of them, that almost always solves the problem for me
