If it's reading 12volts while running I'd guess your alternator is probably bad (which would explain the heavy steering if the alternator pulley is locking up putting drag on the engine/belt), it should be closer to 14volts. I would ignore all codes until the voltage is corrected, electronics can be sensitive to that and cause false codes.

Damn alright I’ll try to get the voltage right and see what’s up afterwards. I’ll update again tomorrow once I tinker around a little bit.

Nope, swapped alternator AND belt and the voltage looks good. Still giving me codes p010c and p0444. Same idle at 1k rpms and can’t pass 2.5k. Basically everything is the same and at this point I’ve put new maf sensors alternator and belt. I’d also like to ad the sometimes when I turn the car on and give it gas the rpms drop as if it’s about to stall.
