05 5.7 hemi throws code p0300 all the time and stalls occasionally. i have replaced numerous things and nothing has fixed it yet.
plugs (stock), wires, coil packs x8, trans solenoid pack(had a trans code), egr valve, fuel pump(because it was 2014 advance auto), crank sensor, iat, and throttle body cleaned.
i have gone between different tuning (edge tuner) after code erases and part replacements.
new symptom today is steering, its very hard to turn when sitting, since i see fluid moving in the res. i think the rack is breaking down. i wonder if a failing rack is causing the occasional stalling and when it stalls or bogs down the p0300 comes on. (i haven't been able to reproduce the stalling).
trans... on first start up or after sitting awhile there would be no gear forward or reverse until a few seconds later. the pack was suggested to fix the issue but now seems more like a front pump wearing out. filters were changed and are seated properly.
I'm basically trying to figure out why it stalls and has a random misfire. I'm working to get a second trans rebuilt. Some knowledge that i may not know would be appreciated.
