So I've replaced my MAF and WOW! what a difference! The only outstanding issues I have are when sitting at idle it will rev steadily from 900 up to 2500 and drop back to 900 smoothly. This happens every 45-60 seconds. The other thing I have going on is when cruising if I take my foot off the gas pedal the engine bucks for a second. Kinda like its saying "HEY keep it going!"

Here's the work I've done recently (in order oldest to newest all over the last two weeks):
Replaced AOS
Replaced oil and filter
replaced the spark plugs (gapped new at .032)
replaced the MAF

Thoughts and suggestions?

Thanks!
Mike
