My carens present odo reading is 35t km m/t, done the 35km pms. My problem is when the air cond is turned off while accelerating from 2nd to 3rd gear or when accelerating during 3rd gear the engine some sort of jerk or pallado when accelerating, does this have something to do with the egr. Have both my fuel fiter and air cleaner change during 20km pms. Please help, thanks
