Was hoping to hear from someone very familiar with the fueling systems and what might be causing it to run rich just at idle. The car has only 19,000 miles, new plugs were put in about 2,000 miles ago. I hate to go the effort and expense replacing the injectors and then discover it doesn't run any differently. The secondaries are wired open, if that makes any difference.
Some states use the treadmill and other use just a sniffer with no treadmill. That is why SOME folks pass. Put on a set of random tech or flowmaster hi flow cats
