Any troubleshooting suggestions before I drop nearly $200 on a GM MAF for this car? I unplugged the connector and didn't see a hint of corrosion thanks to good ol' weatherpak seals. I know it could possibly be a wiring problem, but given the intermittent nature I don't think ohming out the harness with a multimeter is going to tell me anything. I'll be disappointed if I change the MAF and the problem is still there.

I guess I should go drive it around after reseating the connector.
