    I have a 2004 Jeep Grand Cherokee 4L just recently I went to start it and it gave me a hard time, once it was running it was rough and when I put in gear it dam near felt like it was going to throw me out of the drivers seat. I put a code reader on it and got P0601 Internal control module fault and P1494 Leak Detection Pump Sw or Mechanical Fault Incorrect input state detected for the Leak Detection Pump (LDP) pressure switch.I replaced the ICM that code P0601 is now gone but problem still exists, one side note I did change the spark plugs and 2 plugs where a bit wet has anyone seen or had this happen to them any help is greatly appreciative...
