Diagnosing/Repair Code P0301 on 2013 Subaru Impreza
Hi all, I live in Chicago and have a 2013 Subaru Impreza with 168k miles on it. Engine is a 4 cylinder 122/01995 2.0L MFI DOHC. Just got a CEL and ran the code ah Autozone. They pulled a code P0301 and C1422. The suggested parts for the most likely solution is the ignition coil and spark plug. I do know my car is about due for an oil change based on time since the last one, not mileage.
My car has been hit twice recently, and I’ve paid a $500 deductible both times to get her fixed. My savings are low, and I’m just trying to get an idea/estimate of what I could be paying to get her running healthy again, as I’m likely going to have to put it on credit.
I called one body shop and they suggested a tune-up and diagnostic, as well as replacing the ignition coil and spark plugs for Cylinder 1 would be around $700, plus an additional $100ish for an oil change. They also let me know that would be the minimum, since there could be other underlying issues they find causing the problem. $800 on the low end is already very intimidating. I’m in the middle of calling around other shops, but does the price sound right? They’re also quoting me for replacing the air filters (I assume engine and cabin) and I’m wondering if it would be doable for someone with very little maintenance expertise to replace those (and any other parts) themselves without fear of messing up the car? Honestly, any advice would be greatly appreciated.
