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???

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.
