01 S, Multiple CEL's and the rabbit hole

[fishski]

Thanks for the help everyone. Problem is fixed. 1/2 my fault, 1/2 bad pre-cat B2 02 sensor. I did not fit the intake/plenum correctly on the bottom of the tube when I reassembled my TB after cleaning. I thought it looked good but it wasn't on 100% and created a vacuum. All is back together and it runs like a top. Thanks again.

Awesome! The first time I removed those parts it was a challenge getting that bottom to seat. The next time I removed the parts I sprayed a little lithium to encourage a smooth connection.

Glad to hear you're back on the road. Nothing like a nagging challenge.
