Hello peoples,

Just did the VVT fix on the MS6 this past weekend. Started her up and she sounds good at idle. However, when taking the car around the block, she sputters anytime you go into boost. Vacuum is OK, boost is bad. I'm going to hook up the Accessport and take some logs, but would like some thoughts around what could be wrong. Any help is appreciated!

So I pulled the IC off to put in new spark plugs, and I found a loose ground on top of the CDFP. I put in the new plugs, cleaned up the ground and tightened it. BOOM, the car works flawlessly now. I'm going to compare the Cobb Logs from the MS3 to the MS6, but I think we're in the clear.

damn i thought that was only a ms3 problem... glad you got it fixed! I miss mazda-land
