i recently took out the air silencer form my MAS a lil while ago, i forgot to replug in my wires to the MAS, and drove a bit....ran fine, untill i stoped back at home and had a very bad idle. So i put in silencer angain and CONNECTED plugs LOL. Then my car ran greta for a week or two....now the idle surges badly, like to 2000, then drops to under 1000. But only when i stop completely, and turn off lights or pull up e-brack er something....then it starts, BLAH im so annoyed.
 
Just a thought but maybe you should try reseting the ecu. Maybe thatll put all the electronics back in sync. Just disconnect the battery for a minute and then hook it back up. Hope that helps.
