Weird surges and jerks while driving
So I have a 98 ZJ 5.2l V8 with less than 140,000 miles on it. After the jeep gets warmed up driving down the road it will randomly jerk and the rpm’s will go crazy. So I thought throttle position sensor or idle air control valve. So I replaced both. It’s still doing it. Any ideas? Oh and idling at a red light or stop sign the rpm’s drop very low and the vehicle struggles to stay running. I usually put it in neutral til I’m ready to move again. I’m not a mechanic so any help at all would be greatly appreciated.
