I have SDD , Launch , ELM... you name it 🙂 No error codes but the most stupid is that none of them will measure injector flow rate.
Drove it now for 30km and when I came back I let it idle in the garage for a bit and then tried to see where the engine shakes mostly and it is at exactly 1800rpm.
There I can feel it the most, and I can feel the engine shaking in the steering wheel or if I hold my hand on the car , for ex. on A pillar.
I also tried to hold Park Brake by holding the button up , put it in D and rev it slowly slowly up to 1200 rpm. When under load I can clearly hear a knock / bang like sound coming either from engine or .. or .. maybe from torque converter... hard to say.
I have also tried injector cleaner , tappet additive , no change. I will probably pull the injectors next week and change the seals , I can see number one on the left bank is a bit wet around ..no puddle but I can see moisture.
Most irritating is that I can hear the "knock" or tapping sound while I drive and because the damn Falken winter tires are noisy and tapping on the road also , I can not deduce where the sound comes from exactly. Planing to mount the GoPro in the engine bay and record while driving.
