OK UPDATE!!!!!!

I went to Autozone at lunch and bought CRC MAF Cleaner spray. I can't tell you how much of a difference this made. All I can say is WOWOWOWOW ! My car feels alive again! It accels faster, the engine has NO more knocking at all, the muffler really purrrrs now at stoplights like it didn't before, its so smooth now when I drive.

My MAF must have been really dirty from my K&N filter and I had no idea. Thank you for this post!!!! Plus, it only cost me like $5.99 for the bottle. I was so excited with the results I went over to my parent's house and did it to my mom / dad's cars.
