I decided to clean my MAF sensor as I had code P0102 come up. Voila the check engine light instantly gone. I'm cursing now because I'm thinking "$500 bucks wasted on the dealer for nothing fixed!", however I go to turn on the heat in my car and in 3 seconds the check engine light comes on again and the car shuts off. I turn it back on with heat off and it runs like a champ. This is frustrating as hell.

 

I have no idea, but the guys on here will need to know what year? D1 or D2? and how many miles on it?

 

2004, 56K miles

 

Go to any local auto parts store and have the codes read, then get back to us with the code numbers.
So for anyone reading the post, never ever try and clean an Bosch MAF, it desn't do anything but prolong the replacement that is needed.
Call Tony at Cerrones, 650-365-4145, he will sell you a replacement for around $130 plus freight, install the new one and go have your codes cleared.
