P2198 O2 stuck rich

Have a code for an O2 sensor
P2198, B2 S1 stuck rich. replaced the sensor and the code came back instantly. i did clear the codes after replacing, I’m about to double check the wiring now.

anything else i should be doing? don’t have vcds with me right now

You should probably be looking for a vacuum leak.

really? i did pull that the fuel rail and injectors. looks like it isn’t totally sealing on one injector. about to order o-rings now.

any other input out there?? thanks euroswagr

You might try Mr. Injector bjcda2000@outlook.com . I got a complete kit to rebuild all 8 injectors for $39.00 shipped.

It’s hard to tell but if the code comes back that quick it sounds like a vac leak. I agree with euro
