Hey guys, this is my first time posting on a car related forum, so please, go easy on me haha
I bought my first Volvo on October 2020, with only 90k km and in really good shape, and since then Im reading here to find help with my issues.
The problem is that the car feels really low on power, 1st & 2nd gear are good, but when Im either on 3rd 4th or 5th(M46), while foot to the floor, it hesitates a lot, its like Im not accelerating at all and after some secs power comes back again, usually happens more when going slightly uphill.
The consume is super high, I got 13L/100 doing 80-100 on highway.
Could it be that because the car was barely driven in the past, it drives so poor now?
The previous owner, one week before selling it to me changed all the filters and oils + timing belt(with 70k km).
I changed the sparkplugs (gap as I rode on the Volvo manual) and wires. Cleaned MAF sensor and throttle body. The hose that connects to the TB had some oil in it (is it normal?).
Today I checked the OBD and I got the following codes:
Fuel injection 3-4-4 & 1-2-1
TCU 4-2-3
Can you guys help me with this to get in the right direction?
Thanks in advance for your help and sorry for my lack of car knowledge, Im really new to this world.
EDIT: Idle stays usually high, between 1-1.5k rpm
Also, checked the injectors resistance and I got 2,7ohms on each one of them
