So my CEL just popped on this weekend. I didn't notice any power loss, but I didn't drive much since I the light came on. I'm due for a tune up anyway, so I'll be dropping a grand on maintenance... I wish I had the tools and knowledge and time to do all this myself, but I've started a new project on a MR2 and will be putting my time into getting that bugger up and running well. I'm still planning on having the VX trail ready for the coming few months!
