will code p0420 make my crv buck when driving i changed the spark plugs and still does it. at first it would only do it when it got warmed up now it does it all the time and if i let it sit when its on it stalls and the rpms fluctuates.
My 2012 LX AWD is bucking under acceleration. At first, it only did it after a cold start if you didn't let it warm up for a good 5 minutes, but now is happening more frequently. If you chop the throttle, then get right back on it, it stops doing it. Any ideas?
