Hey , I´m new here and on a quest for answers . It goes a little like this ...
Type Volvo C70 coupe 2.0T . Year 2000.
Jumped started the car 2 weeks prior to problem (left on my lights.)
Changed oil 1 week prior to problem.
Then just the other day..
The engine starts up at the first go but stutters a bit.
When starting up revs go up to 1200 drop , does this again then settles at normal idle. Maybe this is normal ?
On acceleration the engine struggles a bit ,there is no full power.
Heavy vibrations in steeringwheel.
Does run more smooth at higher speeds ,vibrations fade away.
Engine does not run smooth as normal and sounds a bit off
Exhaust fumes smell like petrol .
So this all gives me the P0013 and P0305 code, what is the root of the problem , please and how to fix this.

 

P0305 #5 CYLINDER MISFIRE
P0013 EXHAUST CAM ACUATOR, OPEN CIRCUIT BANK 1


Has the timing belt been replaced? How many miles/km on vehicle?
Find a good Volvo independent mechanic, like I have for the P0013 repair.
