I replaced my MAA myself

symptoms: CEL hadn't come on yet but during hard acceleration but not in kickdown phase supshifts were delayed and abrupt.

CEL light came on a few days later, disconnected battery CEL stayed off for about a week, then came back on

I checked my intake runner and found a tear so replaced intake runner, disconnected battery to clear CEL, but light came on a few days later.

Tested car and found at speed around eighty MPH cars transmission acted hesitant and shifts were trashy, thought trans was the problem

Went to this sites Shopforum and learned about codes and MAA.

Purchased a MAA from Fastlane carefully removed old unit careful not to tear or brake intake runner, just plug in new unit disconnected battery, reconnect and start up car.

Everything has worked great ever since - 4 months now - just put in a new airfilter which some say a dirty filter can harm MAA.

Good idea to check battery fluid level, vent hose, mounting, chk for any acid spill so I think disconnecting battery is the way to go
