Hello everyone , i am new here and already have a major problem that i need some insight on, i have a 2003 liberty renegade with 178000 km on it and just recently the check engine light has gone off and i notice that when its in 4wd it gets sluggish and starts to bibrate almost as if its got no power, ive used ti numerous times off-road and always had it meticulously maintained. anyone with any similar problems ? or might have an idea what it could be .. the jeep runs fine in 2wd btu obviously the check engine light is on.

 

You can obtain the Check Engine code by turning the key.On-Off-On-Off- and leave in ON position,
The code P00441 (example) should be displayed in the digital odometer.
Post back the trouble code!

 

wow i cant believe how many popped up so here goes
P0132, P0300, P0301, P0303, P0455, P0305, P0838

 

132 O2 sensor circuit high voltage (bank 1 sensor 1)
300 random multiple cylinder misfire.
301 cylinder 1 misfire.
303 cylinder 3 misfire.
305 cylinder 5 misfire.
455 evaporative emission control system leak (gross leak)
838 four wheel drive switch circuit low.

My first suggestion would be to carefully check for a vacuum leak somewhere. After you find it, clear the codes and see how many come back.

 

hey thanks for all the info .. will check and post back the reults
