Today it was delivery date of my "new" MAF. Went off and grabed it, went to my garage and mounted it on the car.

And guess what, (yea, you already know it by now) engine respons is MUCH better, no missfires AT ALL and with the pedal to the floor it revs to redline faster than ever before. The car now runs better than it have ever done.
Thanks to mercedesshop.com I've saved $700! (A new MAF to my car in Sweden is $1000).

I think i have to go cruising tonight

Edit: I forgot to wrote, I cleaned the MAF with CRC MAF Cleaner before mounting it.
