Hello, so its been awhile since ive posted on here and its mostly cuz ive been stuck figuring out this problem. So at idle the engine shakes and u can feel the vibrations thru out the rpm range just not badly, the only time u really notice is at idle at 1k rpm. The problem started one day when i passed at semi at 120mph on the freeway and it was only for like a min then cruised at 80 mph well when i got to the next town thats when i noticed this shaking. So thought i spun a rod but when i pulled the pan everything was fine and there was no metal flakes, checked timing and its fine, i checked fuel pressure holds at 50 psi, i checked compression and it was 160 across all cylinders dry tested, all spark plugs are firing, fuel injectors are opening and closing and im not throwing a cel code. The motor mounts were all replaced recently and still look good. I do get detonation evidence on the spark plugs but again im not throwing a cel, front o2 sensor was replaced as it went out and the manifold had leaks so i had that and downpipe replaced with stainless steel piping, vacuum checks out at -20hg, swapped ECU, Crank, and Cam sensor but still no fix. Been like this since february hoping a cel would get thrown but still nothing, car isnt smoking either..... soo what do u guys make of it??? Cuz im lost on this
