Hi all,
So a few weeks back I got a major defect on my ER34 25GT Series 1 NA and therefore had to get a roadworthy. My HKS exhaust wouldn't pass, so i purchased a Series 2 Turbo Stock Catback system with Muffler. After I swapped them back over, after driving for 5 minutes or so the Check engine light now comes on. If i drove the car hard it would stay off but if i drove it normally it would always come on. Now its coming on as soon as the car starts up.
I should also mention I have smashed out the inside of the cat so im assuming thats what might be causing it? Although, the sensor for the exhaust is closer to the engine i think?
Someone told me i should disconnect the battery for 12 hours as that resets the ECU which will then allow it to re learn everything.
Basically I'm just asking for help getting the light off?
Any ideas or comments would be great Thanks,
Justin
