2014 GMC Terrain SLE 2.4L (K LEA Gas) 6-spd (6T70) — 2GKALREK1E6381323
P0300 — Random/Multiple Cylinder Misfire Detected
Rough Running At Idel

I am looking for a cam crank wave form for this car. This engine was patched together. I performed an in cylinder pressure transducer test and found exhaust cam retarded (so I believe) I would just like to confirm. Any help with a known good wave form would be great. If known let me know if the vvt's were plugged in at the time of capture.

Car will stall if accelerator is gently depressed but my customer drove it on the highway down to me 45 min no problem. Also slightly low vacuum.

Also I'm not 100% confident they assembled this…
