CEL VSC Trac light on engine shaking....
 

Greetings...
Toyota 4runner 2005 V6 4X4 200K, Check engine, VSC and Trac light came on, did diagnostic came out that one of the catalytic conv sensor was bad, so we replaced it...we test drive it and after a rapid strong acceleration all lights came on again...engine shakes/stalls on idle and when accelerating (it feels like is misfiring), also when accelerating sometimes there is a strong shaking and Check Engine Light starts blinking....your help would be appreciated....Thanks
