hope this can help someone.M30 ran so rough that the plugs fouled in 1 hour running.Changed out the plat.4 plugs that have been in the car for 2 years with no problems with NGK.Switched CPS(getting spark and disparate)no help.Cleaned ICU,checked ICV.Noticed when I put my hand in front of the MAS tried to run.Switched out with a spare and runs great.Old tested good.For all with stubborn starts and super rough idle MAS cleared mine out.
