Misfire So I just got a 2001 camaro z28. Has 67k on it. Was told the car had its engine replaced with a 10k motor. Has 40 psi of oil pressure warm. I was driving today as it was raining hard and then I got back home. About a hour or two later I drove it again and it began to misfire and a SES light came on. Went to advance auto and got the following codes:
C0550
C0896
P0151 bank 2 sensor 1 intermit
P0174
P0300
P1380
Misfire
P0174 bank 2 system too lean
P0300
P0300
I know there are duplicates. He said there were multiple. It had a abs light on along with the brake light and the traction control being turned of. Probably water getting into the coils or o2s or a bad knock sensor. But if someone knows more let me know

I’ve got one of those lights you put in between the plug and wire and it tell you if there’s spark. I think I’m gonna test it tomorrow and put dielectric grease everywhere. Then prob pull plugs and see what the gaps are. Maybe even compression test it

So I tested the injectors and they all were the same resistance. Then I pulled the plugs and they were .040. I regapped it to .060. That’s what owners manual said. However when I went to drive it again it still misses. It wasn’t as bad when cold. Then when I get it warm i could tell it had a misfire. Scanned it and P0300 came up again (I cleared the codes before driving). When I came to a stop it idled weird. Anyone have any ideas?
