Here's a pretty significant clue. Yes you say you cleaned it. try cleaning it again. Th
ere's something wrong with it.

he bought a maf from ebay. didnt someone from here do the same thing and their car ran like poo?

(unless he happened to get an oem one :dunno: )
Is the one you bought OEM? Was it new? Used?

Do you know anyone else with an E36 that you can swap MAF's with to test?

Stomp test

search for TCM
Transmission Control Module
What good will the stomp test do the OP with a '97 328? I was of the understanding that was only for OBD I cars :dunno: Yes I know perfectly well, just not trying to start a fight.

If it were the vanos.. it would be making a significant amount of noise..

Clean, Clean, Clean the MAF.. remove screens on MAF, use spray FIRST, (and LIGHTLY with q-tip if necessary) clean the element.
Clean Throttle body
Clean Throttle position sensor
Check for vacuum leaks
Check the hoses that are plumbed into the boot on intake

Disconnect, clean, lube, and reconnect all associated electrical connections.

Why don't you put that in your sig? Then you could just put "Read below". ;) :rofl:
