Strated the car for the first time today. While it was down I did new plugs, painted the bay to match the car, Headers, Greddy evo2 exhaust. Started her up and she ran great, no check lights. Shut her down after a min. and started her back up. The Service light came on, all connects look good. Im starting to think it might have something to do with the EVAP box I had to relocate for the exhaust. Anyone have any ideas?

 

Could be the EVAP box, could be something with the oxygen sensor when it got replaced into the header. Maybe it got damaged. yo need to get a diagnostic check to find what the problem is.

I recommend this: www.digimoto.com. For the same cost asa trip to the dealer to run a full diagnostic,you can own your own tool.
