Don't forget to recode the injectors when you swap them.

Very Interested in hearing what you find out.

I'm currently dealing with an issue where my
-oil also smells of fuel
-misfires on Cyl 1,2,3
-loss of power
-very strong vibrations under >5% throttle
-very rough idle & stalling (misfires)
-black soot out the exhaust

I pulled plugs, all were dirty, #2 was wet & smelled of fuel.
^Sounds like classic bad injector(s) right? (running original Index 9's)
Took to dealership for warranty replacement, they swapped out O2 Bank 1, Sensor 2 (at outrageous labor costs) and it's running normal now (1 day & 50 miles later).
I'm just waiting for those codes to show back up... I want those injectors replaced for free.

thank you for your input.

I have a little hope now that the O2 sensor is bad on bank 1.
I will of course do the re-coding
I will report tomorrow what i did.

Tell me. Is the smell gone?


Still curious what a bad O2 Sensor may do.

I am not having any Codes @ jokers_greg
