Good morning all I wonder if someone could advise me on what to look for with the above problem. The car basically "stutters" 3-4 times in 2nd and 3rd gear (probably other gears but I can't feel it as much) between 2300-3000 rpm. It shows no code on my Vgate reader, the only code that ever comes up is for the brake pedal switch. When the car stutters it doesn't go into limp mode or flash the yellow coil light. And apart from the stutter it drives great. I've cleaned the egr valve plus the air sensors. I think it could be a crankshaft sensor but I'm not sure, I would hay thought that if it was it would put the car into limp mode and show up on the dash and code reader.
