Hello Experts in the house, I need your advice. I have a corolla 2005 I bought last year(Nigerian Used), I put it up for Uber when I first bought it and had to take it back after 2 months after seeing the deplorable state the guy had put the car in. Lately I decided to put it back on the road for Uber again and did some fixes and changes to make it Uber standard.
I did a full suspension change, changed the whole AC unit( compressor, condenser,evaporator) then had the mounts changed cause it has been vibrating, but even after the four mounts have been changed the car still vibrates. The plugs were recently changed(I cannot ascertain this coz my brother took the car out, it developed some problems and his mechanic claimed to have changed the plugs and a coil).
The car is now in shape but the Uber driver says the vibration still persists. What could be the cause of this annoying vibration? PLEASE HELP!!!

Check the injectors (nozzles) and the air filter. You can also scan the car for possible error codes.
