I have an 03 Jeep liberty automatic 3.7 great vehicle with no issues as soon as we paid it off a matter a weeks its been breaking down
isnt that how it works..
Its running rough, idling rough the other day we went to town and barely pushed 45... shut it off started it back up .. hit the gas alittle then it ran ok coming home.. wierd.. i dunno much about jeeps this is my first one..
check engine light comes on . the other day it stayed flashing. right now its just solid..
we had codes p0300 p0301 p0306 .. general misfire then the 301 cylinder 1 . cylinder 6 so forth changed spark plugs checked individual coils swapped em around to see if we got different codes.checked for wear etc.. reset it the hub drove to work this morn check engine light came on bfore he left the end of the street.. got to work now its just code p0300.. now but ran semi ok there..
i hear this model doesnt doesnt have an EGR valve would explain why i couldnot find it.. but . that would b my first guess. to check it , . im hopin nothing is wrong with the valves themself.. So what does it have that could cause this problem.. anyway to narrow it down without nickel and diming us to death with a process of eliination.
any help or guesses would be Greatly appreciated. im at a standstill..
