Message	I'm limited as to my knowledge in this area, so hope someone can help. Vehicle info: 1990 5spd twin turbo 73k. I've performed the ecu diag for both exhaust gas sensors, and determined the passenger side is reading rich. I have not been able to find any leaks in the intake. In looking at the 6 spark plugs I only confirmed what the diag of the sensor tells me. The plugs installed prior to my owning it were the bosch 4 prong platinum so I installed the correct ngk plugs as well as installing a good sensor I had from my last z. The vehicle does have a slight exhaust leak but its after the sensors before the main cats. Im probably missing something obvious, and yes I searched this for some time. Maybe my wording in the search is hindering me. So in summary, passenger side sensor reading rich all six plugs are fouled and I haven't been able to find a leak. Thanks in advance for any help
