Tail pipe emissions are Idle - CO-0.30% **O2-3.61% **HC- 0493ppm 3000rpm CO-0.41% O2-2.33% HC-0089ppm Looks like at least one or a combination of all three cylinders on that bank are passing o2 and fuel. Backed up by o2 sensor reading low. If you confirm the plugs and injectors are firing with a scope, then surely it can only be a mechanical engine fault on that bank? |
