Our jeep started to feel like a gas engine with a mis at low RPM. It has now thrown EGR code P0489. It has also had a stored code P0340 camshaft sensor.
It has 148K and all oil changes have been with Mobil 1 ESP 5w40. The problem seems to get progressively worse when the engine warms up.
Any ideas would be appreciated.
