I don't understand. I've been fighting some idle issues after a TBSS intake swap and a bigger cam. During the scan cable process, Blackbear said I had a small leak probably at the intake but the tune is good to go. I sprayed starter fluid on a cold motor around the intake and TB and didn't hear any changes. I found a weak spot on the evap line, my EGR delete wasn't capped off properly, and the MAP sensor wasn't secured well enough. I fixed all these issues and now have p0300. Torque shows it's happening in all cylinders A LOT. After I fixed those leaks the idle issue went away except now it misfires terribly.
It has new plugs and wires, I've triple checked every injector and spark plug wire and nothing is crossed.
Is it a fuel delivery issue? The FAQ I used as a guide to modify the fuel system mentioned the C5 filter/regulator holds a static 58psi and I should tell the tuner to account for that. Well I didn't do that because I overlooked that on the FAQ lol. This doesn't make sense to me since I did a scan cable tune. Would he not see this?
Do I need a bigger fuel pump to power the 36# injectors that are bigger than the stock #26 injectors?
Is it timing? I had a timing chain dampener but someone I talked to at Summit said I shouldn't need it. Now I'm wondering if he didn't know what he was talking about.
I would be happy to post logs if someone can help me diagnose. I don't fully understand what to look for.
