Hi guys
Bit of a back story.
Have performance and acceleration issues on my 1.6 Stilo. I have a Check engine light on. I have a elm 327 scan tool and put it on. It read O2 bank 1 sensor 2 heater malfunction.
So direct replacement. This month I planned to replace however we are too in lockdown and no spares shops open AS WELL as fact that I'm on a no work no pay.
While my stilo parked in driveway and not driving anywhere I noticed when pulling the car in and out of the garage,she has a random misfire. Spoke to some peeps and they said don't jump to O2 sensor just yet. Check that CAT may be blocked. I checked videos online and My symptoms are same as blocked CAT.
My question is,since my O2 sensor fault is post CAT,could it be that the blocked CAT is causing the O2 sensor to give in or give incorrect readings?
I removed it once and saw black residue on the sensor post CAT. Pre CAT was clear as day.
When revving i do get a clear white ish pale smoke coming from the exhaust with a fuel smell.
Thanks again!
