So, after thinking the car was running sweet and well, on the trip down to Dover, it developed a slight misfire on cylinder 7&8, this was after 30 minutes of being in the car, at pretty much constant speed, though it wasnt all the time, just occasionally you would feel it. Stopped off at a services for 10 minutes and when it started, it came up with ‘slow down’ and blinking CEL light showing all of Bank 2 misfiring. Reset the codes but it came back pretty much straight away. Then after a while of driving it all disappeared and normal service was resumed. I have also had hot start issues occasionally also. Car would crank but not fire, then after turning the ignition off and on again, it would eventually fire with a tickle of throttle.
Want to get it booked in for an SD3 somewhere when i return, but any suggestions as to possible cause? Unplugged the MAF and running seemed lumpier. I replaced the front 2 oxygen sensors, but not the rear 2. Is it possible these are causing an issue. One of the faults was something like swapped banks.
Seems fine at high RPM, its just low/medium its doing it. Could it be crank sensor or something?
Any suggestions welcomed
