Hello, I recently got myself a Dayz 2014 model and it's 58k driven. I have noticed the car shakes or vibrates a lot when its idle like on a stop sign in D mode or when I put it in reverse gear with brakes pressed. Shown it to a mechanic and he did tuning over all. Cleaned throttle body, fuel injectors, plugs, catalytic cleaning, changed air filter and AC filter as well. Oil and it's filter was done recently too. Vibration is more intense with AC on. Got the load check too and AC technician said its fine. With AC off, its bearable.
The vibration is now less in D mode in idle but it's still the same in R gear. Mounts seem to be okay as well. Also got checked the gear fluid and it was okay too. I also fuel the car from a reputable pump. Using engine oil Toyota 10w40.
What other reasons could be causing the vibration? Car runs fine and smooth beside that. But this vibration is so annoying and make me feels like that I am driving some old manual transmission car. Looking for helpful advices as I feel like I wasted my money.
JazakAllah
