I have a 1997 BMW 328I , 5 speed. When i'm in gear and accelorating the car feels like it's missing or like when your in to high of a gear and you should down shift. This happens between 11/2grand and 21/2grand. So I put the code reader on it and here's what came up: 4E-"AfterCat oxygen sensor voltage Cyl#4-6", CA- "Oxygen sensor control limit Cyl#1-3", E3-"Oxygen sensor adaption limit Cyl#1-3", E4-"Oxygen sensor adaption limit Cyl#4-6", E9-"Catalyst efficiency below threashold Cyl#1-3", EA-"Catalyst efficiency below threashold Cyl#4-6", and FE-"EVAP large leak detected". So does anybody know why make car feels like it's missing with I accelorate?
I think the most common problem with the EVAP leak is a loose gas cap. Now I would never suggest anyone to do this, but sometimes when someone gets those faults, someone will drive at WOT for a bit. That sometimes clears the problem. I find it odd that all those sensors are coming up with faults. I'm sure someone will chime in. But unfortunately 10 years on a cat may seem about right.
