First of all, let's talk about the easy thing. The light dimming is due to a weak alternator that is overburdened. Even though this is still present in my 2006 Cuore CX automatic, I disconnected some aftermarket accessories like fog lights and alarm horn and this improved.
Next, the big thing that is the vibration.
Brother mostly in auto Cuore the engine mountings get weak after a year or two, I have had the car for 9 months and changed the mountings twice.
If your car is getting vibration in R and D, check the automatic transmission fluid level. Same issue was In my car suspension work was done and the mechanics don't bother to top off the ATF. When I poured ATF, the now Alhamdullilah has almost zero vibrations now.
If ATF is filled, then get the transmission mount inspected. I was also shocked ke itni jaldi kese toot gayi foundation but quality kharab thi us foundation ki the new foundation is very good.
Agar vibration continuously same hoti tou carburetor check karwatey for kachra, because ye masla bhi hua tha meri cuore mein, lekin your issue gets worse in R and D.
Finally, if nothing does it, get your idle RPM a little up. Your car consumption will increase a little but fuel saving is not worth it if your engine is shaking your car's dashboard on your face.
