FIXED: If anyone else is having these problems and stumbled across my topic here on the forums, I did take it to dealership, the tech deduced the car had a faulty ECM which was causing random misfiring and timing issues, luckily for me it is not a timing chain problem as I had no codes for crankshaft position sensor or any VVT solenoid codes. The tech also discovered my oil pressure sensor was telling the ECM that my idle oil pressure was 127 PSI, the tech deduced that this faulty sensor somehow ruined my ECM and both were replaced after all diagnostics were done as-well as GM having been consulted. The total cost for the sensor, ECM, and Labor was $1491. I know I could’ve done this job for less than $400 but I was honestly tired of scratching my head on this car and happily coughed up the extra grand in part mark ups and labor for someone else to make it their problem. The car runs amazing now like it should my exhaust pitch has changed as well as the exhaust note. Everything sounds a lot more crisp and timed close together as it should be.
