i unplugged my map sensor today to experiment because i was still having periodic bogging and the car runs like it should.i believe the map sensor has been my culprit all along even though no cels were thrown before i unplugged it.definitely look at the map.

First post :) not a proper intro, but will post one later. Just installed the stillen gen3, and on my test drive same thing happened to me. Took it home and tore it apart. Turned out that a slice of rubber came off the driver side K&N filter and got wedged in the throttle body! Was not a happy camper. The 3 hour job turned into a very swear filled 6!

Sounds like intermittent CAS failure?

Ok i think i was able to duplicate the incident
For a while now i hear this grinding noise when i take a long sharp circular turn while stepping on the gas(it disappers when i let go)
At first i was thinking wheel bearings so i didnt pay much attention to it
So today i took the turn while accelerating and if course i can hear the frinding noise
And as soon as i exited the curve and try to accelerate the car bogs at 3500 rpm and wont let me accelerate further
Now im worried.. Can anyone shed some light? :(

Found this post reply #19 is the exact same situation i have
