ok so an update to everyone who is interested in helping.
So i had p0300 and the o2 sensor code, replaced o2 sensor from the oreilly auto parts, direct fit. O2 sensor code no longer comes up! Thank god! Now could the o2 sensor be the reason I'm getting a p0300 code at 70mph? I hope so because than the fix would be done right!? Right!
So as soon as I take the vehicle out on a test drive I still get the p0300 and flashing engine light at around 70mph, i believe the vehicle is trying to shift from 3rd gear to 4th? Is this a 5 speed auto tranny?
Also my p052 is complete gone due to the new o2 sensor.
So now I get 2 codes pending again. I get a new code P0440 Emission control system malfunction and the p0300. I check the gas cap, it was half broken, so i purchased a new one from oreilly again.
Reset fault codes and drive again. Now i'm getting p0507- Idle air control system RPM higher than expected.
Now the P0440 is gone, but now i have a P0507, and of course the P0300.
I've included a video of the throttle lockup that i'm experiencing. Maybe a good dodge tech can help me figure this out! my hands are tied again.
