I got the ecu reset by a guy he took 500rs and rpm including breaks are normal now. Car is very stable and responsive now after the ecu reset. Ecu reset took place coz he opened the throttle body. And that messed up every thing.
@muradi Bro take a look at the spark plugs that came out. Dude I had no idea who wrapped that scotch tape over them.
Eyes burning issue I believe was because of the leak of the exhaust pipe joint which happened due to the bad Hit on the same pipe having 5 persons in car who never take their own cars out at office hours when it is needed and try to fit them selves on others shoulders weather he likes or not.
Well I am posting this image of the spark plugs. And I have changed them with new ones NGK laser iridium.
I was just very much worried about the loss of the power which I think came back. I drove the car nicely while coming to work now after all this. I will floor it bad later on.
I don't know who wrapped scotched tape to the plugs and why.
