Also, check the voltage and resistance of the O2 sensors with the Duramtric. If the values are consistent, then its unlikely its the sensor. You can also check for a vaccumm leak by looking at the MAF, ignition angle, RPM and all FRA/RKAT values. If the MAF is low, say below 12 and the RKAT is +3 or 4, (should be 0) its a good indication you have a vacuum leak.
