Thank you for the video, that was very very helpful.
I removed the MAF, bendy tube, and TB. The MAF and bendy tube were not too bad. Hardly any dirt came off. However the TB and slum city and the intake was horrible.

Dirty Dirty

I cleaned the TB and intake put everything together and tested the car. It's much better but as I was pulling in my driveway I felt a hesitation. According the diagnostic chart, it's spark plugs next.

The car is at 126K miles. From the reading I have done on the forum, I strongly suspect that spark plugs and wires should be replaced. With the amount of work in that replacement job, I think replacing the valve cover seals should be done as well. Going to get the spark plugs from needswings. Are the magnacore wires worth it?
