Engine light comes on every day with same codes
Posted: Tue Jun 12, 2012 12:33 pm
I have a 2006 Mazda MX5 with one of the first Cosworth superchargers (engine was rebuilt by Cosworth for free). I have completely replaced the exhaust system with racing beat headers,mid-pipe, and Borla exhaust.
However, I every day within two miles the engine light comes on and I get several of the following codes, especially p2035. I have replaced the throttle pedal mechanism ,etc.
I understand this is a common problem in stock MX-5s and that Mazda must update the software. Does anyone have any ideas about how to fix my problem?
