[V8] "Major Surging"

[BBlake1055 at aol.com]

I guess I'll start taking the air box apart and get to the harness.  Yep - I broke it off right at the connector.  I already bought the Audi O2 so I'll either buy a new harness or splice it at the connector.

Thanks everyone for all the help - I should have asked questions before I screwed it up!  Oh well, it's all part of owning a V8 or Two or Three!!!!!
