Update: once again I've never had this issue with any vehicle that I've ever had in my life. But the whole issue with the vehicle was the catalytic converters were completely clogged and I change those out and my driveway along with the O2 sensors and I'm getting engine knock sensors and also getting misfire multiple cylinders which were driver side only, so I went around tested the ignition module and everything in between and then I had the right idea of pulling out a spark plug, extremely carbonized on the driver side only while the passenger side was perfect and so I went up and grabbed some new spark plugs and seafoam came home seafoamed it changed the spark plugs out after and cleared all the DTCs, I had one more group of DTC's pop up which I cleared out via autel scanner that I have and it is now running absolutely perfect even put on my aftermarket cold air induction and I'm loving it now finished it as of an hour ago, just wanted to say thank you to everybody who responded and tried to help figure this out with me I really do appreciate it everybody!!
Everything was fine, then i got to my other development property with the wife, truck ran exceptionally well that night, pulled in and it stalled. Just did a full ignition tune up as it's never had one since factory, restarted it, fired right up, tapped the gas & it sounded like a deep hollow cavity from the pass side engine area and will not stay running, when it does catch it bounces on its mounts all of a sudden, as soon as any fuel is added it dies. I already put dye in the coolant expecting a head gasket leak, i have dye on my dipstick, still need to stop the pan. Everything turns over fine without obstruction. Did a compression test yesterday, each cylinder had 6 revolutions, or as close as possible, wife was cranking i was recording. Cylinder 1-170psi, C3-175psi, C5-180psi, C7- 176 Cylinder 2-170psi, C4-185psi, C6-175psi, C8-170psi. Pressure test is next but does anyone think I'm on the right track or am I missing something here. Lack of engine experience kills my diagnostics & really need some help here to get back rolling as I'm a new contractor and being broke is my specialty at the moment. Any help is much appreciated
