I certainly sympathize with you here, but am out of ideas. Exhaust or intake clogging? Start from the beginning and double check?

on vcds in channel 13 (idle speed smooth runing control) i noticed higher value at cyl #4 than other three cylinders the value is sometimes around 1.84 at coolant temperature 85 degrees and if coolant is around 70 degrees the alue on cyl #4 is around 2.33 i wonder what this means ?? other three cylinders are around zero.
Chitty im waithing for your oppinion what do you think could my problem with loss of power be related with faulty injector? ........the car has no power below 2000rpm
