The only real down side to using a scope, is you have to have a known good comparison. They are few and far between. 40 years turning wrenches and I only "needed" a scope once. For a proximity sensor.
DenverWinger.....disconnecting the MAF and running better in failsafe is a time tested diagnostic. You didn't "need" the scope for that.
Libraries are full of stuff I don\'t know.
