Rough idle and jerking while driving.
Hey peps, new to the forum. I have a 06 GC 3.7 4wd at 93000 miles. The problem with the idle is it seems to shake some what at stops while in gear, drive or reverse about 500-600 rpms. In neutral and park not so bad. The big problem is when coming from highway speeds (55-65)and coming to a complete stop it will do the rough for like 10 secs and dip down to 200-300 rpms wanting to stall. It does it every time I get off the highway. Has new plugs, air filter and fresh oil. Now the jerking only happens in first gear in traffic. When I press the gas sounds and feels like the drivtran jerks and clunks and it does it again when I let off the gas while still in first. Again it only happens in slow traffic. Check the motor and trans mounts they are all good. I'm T a lost on both things. Would be greatful for any advice.
