I took a week to replace a bunch of stuff in a 2003 2.4t v70 to try and fix oil burning / misfiring at idle
PCV system
New throttle body/ecm
sparkplugs (volvo oem)
coils (aftermarket)
fuel injectors (bosch refurbished)
IPD turbo control valve

I went to start it and it didn't want to - it eventually did and smoked white for a few minutes. I figured this was because it sat a week, as it hasn't done that since. But now it's idling rougher than it was before I put anything in, and i'm getting codes for all 5 cylinders misfiring, including one for cat damage? and one for engine RPM sensor cyl 1.... I checked the plugs and they all look fine, coils look fine... what could the issue be? I'm a bit lost on this. It also won't start now unless I give it some gas. I've stopped driving it until I can try to pinpoint an issue here. It also smells like gas when running, and the exhaust is sputtering.

Edit: here are the codes I'm getting. I did just replace the throttle body, should I reset ecu? The rest /8 are just the other cylinders misfiring, but they don't say anything about cat damage or engine rpm sensor.

 

 

I took it to my trusty mechanic, who found that one of the remanufactured injectors was faulty and fouled plug 1. replaced both with the old injector and a new plug and it runs better than when I bought it. Just got it back about an hour ago.
