Answer 1
If you have one of several parameters that are not met it can cause what you have.You'll need to hook up a scan tool that can view live data and have a look at your basic parameters like ect,iat,o2s11,o2s21,o2s12,o2s22,vss,tpv,tpmode. -

unfortunately for me there are no codes coming up??? -
Comment 2
does the scan tool power up when you connect it to the dlc? I've also seen scrambled numbers when trying to retrieve dtcs caused by aftermarket performance chips. -
