past 2 years... I spent more then $3000 on fixing everything.. GA clean air force give me the repair weaver to get my tag.

I am not getting any error code on ECU.

comprehensive components-not ready
Catalyst-not ready
Evaporative System- not ready

I did found out from dealership... after market air filter was making the car to drive too rich.

I had to purchase factory air box and everything is running perfect.
