EHA is working, fuel pressure is good. Also had the cat inspected by the shop that instsalled it. Guy cut a hole in it and looked at it and all was well. I'm jus taking a random guess, but could something be wrong with the throttle, throttle body, throttle body sensor? I am barely able to get up to freeway speed (70 mph), it takes a good 45 seconds to 1 minute to even reach 70 mph. If I try to floor it, the economy gauge goes all the way to the red and the car rapidly loses speed. If I easy up off the throttle some, but not all the way the it will slowly pick up speed again.
