Hi guys,

This is my first nissan Tiida 2014, i bought from someone.
1. There was a problem like aligning or balancing tires, but I check everything normal. And when I drive more than 80kmph begin to vibrate whole car and try to slow down same issue. Also pulling to right side slighty. 2. Accelerate the power loss on startup and switch to gear D, R does not move for a few seconds or until pushing the acceclerate. After checking the ignation plugs, it was bad, then I changed 4 plugs and cleaned the upper part once everything was fine and I had failed again. As the machanic says the coil is good.
Can you please advise
