1998 V70 Rough idle, multiple injector circuit/open codes

Post by PagodaMomar »

My V70 started running and idling rough the other day as I decelerated off the freeway. I was able to make it back home. I pulled the codes when I got home and i've got p0202, p0305, p0205, p0204. Three of those are injector circuit/open. Not super familiar with fuel injected engines and was wondering if anyone hade any idea what would be the cause and solution to this problem. Also is the misfire on cylinder 5 related to the injectors.

Hi and welcome to the forum.

The P0205 likely caused the P0305. Maybe the injector relay is going bad.
