ScanMaster has shown up with a never seen before reading "AP 947".
This comes after the O2 reading for the factory NB and does not disappear upon restart. Car started surging anc bucking tonight after running perfectly for about 2 miles. No codes at that time. Pulled out ECM and removed then reconnected wiring harness and re-aligned PL. Restarted car and it ran smoothly with none of the key items, such as TPS, IAC, RPM, Temp, etc bouncing all over the place as they had been doing. Code AP 947 showed up then.
I run PL with the TT SD chip.
Please advise what this code means.
Thanks.
Phil Engle
