Ok im not sure what to do? I want the P0300 code gone for good. my question is if I get a aftermarket tunning system like AEM or UTEC (or any other brand for that matter) will it go away?

Or will ECU FLASH work? and how do I go about getting it?

Also With one of these systems will my OBD2 prot still work for inspection in the state of texas?

Thanks for the help.

 

Which rom version do you have?

 

Not sure if any of those will work. but if you find out that the utec works and want one i have one that is just sitting let me know if you want it. I went with ECU flash because i went with a mellon tune.


Good luck

p.s. i only get the code like once a year if that with just ecu flash and the utec but set to map 0 (bypass mode)
