Hi have recently changed my tires from winters to summers. They come on separate rims and i have had them on before so not new new to the car and a few weeks back i had new break lines and fuel lines put in. These are the only changes that have occurred. About 2 days after changing my tires i have noticed that my VSA light and the warning triangle with the ! comes on on the dashboard every time i drive above 60 km/h the car does not behave differently or i cant notice anything weird. I do have the check engine light on but i had it checked and it says its O2 censor so I am wondering what this could be as if I drive below 60 in never comes on the moment speedometer goes above 60 VSA lights come on??? Please help if anyone has any ideas.

Also the car accelerates a bit funny kind of giggly i am thinking i need to change sparks and new air filter any suggestions? or will o2 censor cause that as well

THank you in advance I am new and look forward to any of your advice.

 

transmission, start there. mileage on car?

 

When u are accelerating make sure you stare at the rpm gauge in retrospect to the speedometer.

If u see the rpms moving up and down that is the tq converter slipping then grabbing.

When those lights came on in my car it was transmission time
