My 2005 LJ 4.0 overheated on a mud run because of the slurry and mud covering my engine. After getting the engine clean, it would still run a little hot so I flushed the engine,replaced the radiator,radiator fan and fan clutch.Water pump,thermostat,and Temp sensor. It did fine for a few miles and then the engine light came on. At 3200 Rpms the Rev limiter kicks in. The cruise control will not work either. I scan and got the P0016 code. I replaced the
coil pack,
CamshaftSynchronizer(manufactured by crown) along with the Mopar camshaft sensor, Mopar crankshaft sensor, autolight 985 spark plugs. I check fuel pressure and it was at 35psi. which should be 56psi I checked compression and the low was 135 with the high being 165. Thats not bad for a jeep with 225000 miles. Next move is either change the fuel pump or take it to a dealer to see what they can find. The jeep runs strong so I don't want to replace the engine if I don't have to.
