I own a corolla gli 2015 , it has around 135k km on it which I clocked over last 5 years , I’m facing 2 major issues which
1. I’ve always felt that car jumps at speed 40-80 km on a Smooth road , I refreshed the front suspension With new 555 parts and Toyota Thai struts, brand new yokohama advan db552 tyres , balancing rod bushes but the issue is still there ... kia problem ho sakti hai ? Any suggestions

During lockdown I used liqui moly catalytic converter cleaner with a drip to clean the cat con as a DIY , it backfired on me ! unfortunately the drip’s pipe got stock in the throttle body during the procedure and I’had to push it with a screw driver to get the pipe released .... check light turned on , I got the idle relearn procedure done from Toyota however I now feel my car is chocked & it hesitates to accelerate & takes too much load with rpm fluctuation on idle

So that was the only solution

Frankly speaking after spending 20-25 k , I was still not satisfied with the results ..... Got an option of changing with zero meter with altis 1.6 AT hence updated by adding the difference

Do you remember what things have you tried to eliminate that problem? I'm actually facing same issue

It feels that the car wobbles(to be more precise, a person sitting in it moves left or right) on minor uneven road(though perfect on smooth roads). This happens at slow speed.

Have you tried changing lower control arm bushes and strut mounts ? Get the inner and outer axles checked and balanced by a competent machine man (I've yet to come across one during my car repair career which spans over a period of 15-18 years now
When was the last time you got your catalytic converter serviced .... It makes a pretty decent difference on the load bearing capacity and drivability of the car

The suspension components were once pressed(z link etc). Changed the shocks to agri autos(don't remember if the problem was there before, I think it was).

Never got the catalytic converter serviced(don't think it is linked with this problem) but yes overall it might have a good impact.
