Hello, hoping someone here can shed some light on my issue before I start replacing unnecessary parts.
- Recently had a P2098 (post catalyst too lean bank 2) code appear, this was the day after fueling up (yes, premium octane with receipt to prove it). Took car to the dealer, they suspected bad fuel and did a flush.
Same code came back the day after. Mind you, the code doesn't appear until about 30 minutes of driving. Took it back to the dealer, and they wanted to replace my bank 2 upstream sensor. Of course they wanted my firstborn, so I bought a new OEM sensor and planned to do it myself. Next day code P2097 appeared (post catalyst too rich bank 1).
- Replaced the upstream bank 2 sensor, still have the issue.
- Replaced all spark plugs with new OEM, still have the issue.
- Exhaust stinks, suspecting a rich condition.... ?
- Catalyc converters are quiet, don't rattle when operating or when tappin on them.
- All exhaust connections are tight, gaskets intact and accounted for.
- Intakes are connected properly and undamaged, filters clean.
- No vacuum leaks detected.
- Dealer stated they did a full fuel system clean; tank, filters, injectors etc.
- Car runs pretty terribly, loss of power, not smooth etc.
Should I be replacing injectors next? Or???
