I'm just surprised..the O2 makes for much more accurate tuning/adaptation of the fuel system..not only for emissions but for power as well!

All the CIS E Euro cars I've come across here came equipped w/ O2's from the factory.


That aside, have you checked your air flow plate sensor and TPS to see if they're working properly?
