Volvo XC90 T5 intermittent missfireP0300 (P0302 & P0305) please help
hello everyone i really need some help i recently bought a Volvo XC90 with the 2.5L T5 Engine this is my daily runner for the kids and would really appreciate some help
this is the problem on the OBDII
intermittent missfire P0300 (P0302 & P0305) Cylinders 2 & 5
here is what ive replaced so far
Spark plugs (Official Bosch Volvo torqued to 22 ft/lbs and gaped to specification)
Ive replaced all 5 coils and the fuel rail and injectors have all been replaced recently
also just replaced the oil with castrol synthetic 5W 30W
but the problem is still present
ive read it could be the crank positioning sensor but i would like some more opinions
thanks for your time

Misfire in Cold Weather
quick note ive noticed the engine light only comes on displaying the misfire
code during extreme cold weather conditions it has been -20c recently and has
come back up to -2c and the engine light has gone off would cold weather be
the cause of the misfire or should i go buy a compressor and a cylinder leakage tester ???
thanks for your help

Misfire
ok thanks for all your help so far , here is another question,
if the coils, spark plugs, fuel injectors and rails are not the problem
and there is cylinder leakage.... what would be the primary cause of this
what would i have to replace to solve the issue or is there allot of different
things it could be, What are the most common problems with the T5 in
relevance to my issue? new cylinder head and gaskets maybe?
here is some more information ...
when i turn the car over and sometimes get the misfire code there is a strong
smell of gas fumes from the exhaust as though it was not combusted
also the engine nearly has 200,000 km
any help would be greatly appreciated as
i would love to save this beautiful car
thanks for your time
kind regards

Recent Diagnostics
hi everyone , today i plugged the OBD II in again and came up with the same error codes as before in regards to the misfire in cylinders 2 & 5 , but i also found this ( open-loop due to insufficient engine temperature ) can anyone tell me what this could be possibly a faulty sensor?
