Thanks, Dave. Gives me a place to start without the code reader. I have been waiting for a guy I met when I picked up the new plugs that has a code reader, but his cell is off today, probably he is at work.
I'll go check what I can, my garage is DARK with lights off, and I will check all hoses and intake ducts for leaks.
Had that problem on my E-30's in the past.
Thanks again, bud.
