Recently I got my buggy put together and I'm having motor problems. After much testing it seems as though my oxygen sesors on are too close to the end of the headers and are picking up outside air creating a false reading that the motor is lean. The computer responds by increasing fuel injector pulse duration and the motor gets so rich it is undriveable. What have you seen done before to correct this issue. Full exhaust is not an option. My fans turn on by toggle switch so is it possible for me to unplug my coolant temperature sensor and run the buggy in open loop eliminating the input from the O2 sensors?
