over the last 500 miles we have stated noticing a hesitation when gently applying throttle, normally cruising along in traffic or through a 40mph limit. When pushing hard the engine is fine with loads of power and no smoke.
I have an OBD2 reader through my phone so quickly tested it tonight and the following codes are showing.
P0380
P1901
The above codes were logged when I last read the ECU in the winter and I think they both relate to the heater plugs not working. This was illuminating the car and spanner light however only in cold weather and when the engine was cold, you could drive for a considerable time without the light illuminating.
P1614
P1616
These two codes are new and the program does not list a cause, I am assuming they have appeared since the hesitation problem has started, interestingly after the hesitation has happened once or twice the car and spanner light illuminates.
Any ideas would be appreciated, fuel filter was changed and housing cleaned out about 4K miles ago.
