Ok so my cobra is being weird. It's an 03 with 50k. I've had the car a year or so and it's always had the check engine and gas cap lights on..don't drive it much and just never got around to fixing it. I do smell fuel sometimes so I'm guessing the filler neck or one of the vac lines are leaking..it just started idling funny, up n down up n down..and seems like it's gonna stall when the fan kicks on. One day took it for a ride and I had no boost at all..next time I drove and it was back to normal.. Took it out again and no boost..any ideas on what I should do here?? Thanks guys
