Thanks Ronnie....you rock..

i have the grounds both for MSD and the harness on the inner stud. (MSD is and has worked fine for 10k miles)

I cleaned the harness ring connector and tightened everything back up.

Bam...it works. Watched AFR during warm up in the 12's then as soon as it went to closed loop quickly ramped to 14 - 14.5....just like before. I believe this is representative of klambda at idle.

Mark...thanks for the input...but it just seemed like something simple because of the sudden change and no difference in boost AFRs (high 11s low 12s) before or after the problem.

I will check pressures etc and tune next but I wanted to get back to where I was before starting and making other changes
