P0300 hell

update i posted about my p0300 problems a couple days ago i finally gave in and took it to a shop because it seemed like a fuel issue and i didn’t have tools to diagnose any further (they charged me 250 for the diag💀💀🙏🏾🙏🏾) but thankfully the found the issue which was a leaky injector on bank 2 which is what i suspected but i hate parts cannoning so i had to confirm before i bought any parts BUT what i was wondering is what injectors ppl typically go with if not oem because they are 160 a pop so actually fuck that😭 i plan to diy it because the shop is one of the only legit shops for miles so the just price gouge everyone in town knows it but what can we do🤷🏾‍♂️(probably upwards of 2000 for an injector job) so i was just wondering what route others were going for injectors

p0300 hell

I am having a p0300 random misfire and a p0175 system too rich at first i thought it was because of 3 generic ignition coils still on the car but after changing them for oem coils the misfire got better and the car became drivable but now the idle is all over the place and it is still missing as you can see my fuel trim for bank 2 seems to be adjusting extremely negative and my bank 2 o2 sensor data says my afr is lamda= .94 to .96 which is a little rich i am leaning towards a leaky injector but im by myself out here so i wanted more options before i buy parts do you guys think it could be a sensor issue or am i on the right track with a stuck injector i also attached a pick if my spark plugs cuz ik someone will ask they are in order if you look at the from the top of the pic to the bottom before you parts cannon numbskulls start shouting clean maf sensors and trottle bodies, i already did coil packs with oem hitachi spark plugs are a year old and i already checked for vacuums leaks
