2007 5.7 hemi “bucking” when driving
My 2007 5.7 hemi bucks when driving. Engine light came on throwing 1129, 1228, and the throttle position sensor code. Happens when driving more so when I’m not accelerating, more so when I’m going down hill or not giving it much gas. Jerks/ bucks pretty hard then continues fine for a bit. Replaced the map sensor and the engine light went off then came back in after I drove it for an hour and a half and started doing it again. Cleaned the throttle body today, will replace the throttle control sensor tomorrow. Anyone have any ideas? Thanks in advance!
