03 Liberty, rough Idle, Code 14
Hi all,
Doing a little check out of a rougher than normal Idle on my 3.7L Lib.
Nothing looke out of place on a visual inspection, gas grade doesn't
matter, and still runs a bit odd after a TB cleaning.
The "hold the reset" instrument check and code readout goes through ok
and at the end shows 14 on the odometer. Any body have a code chart for
the 03 3.7's?
Other than that, power seems ok.. decent on the freeway. just a little
rough and occasionally low (500RPM) revs. Not all the time, but often.
Typically once warm idles about 600. At the tail-pipe she sounds smooth.
Clean air filter a couple months ago. Since I'm in Vancouver BC, the
rain keeps the dirt down so it still good to go.
Any suggestions? Likely will end up at the dealer... only got 37000km on
it.But, if its a case of somehting simple, I'll save the days wait for
service. The dealer may be able to fix it, but they are mighty slow!
Thanks!

I don't know for sure on that, but on the Cherokee, 14 is the MAP
sensor. That could just need the connection cleaned.

Re: 03 Liberty, rough Idle, Code 14
The 03's (and other 2000 models) have a different OBD computer system
than the Cherokee. Totally different code map.
Thanks for the input though.

The Shop Manuals do not have a "Code 14". However, to read the codes on an
'03 Liberty, turn the ignition on,off,on,off,on, and the codes will cycle
through the odometer. After displaying the last code, the odometer will
display "end".
Also, some auto parts stores will either rent or loan a ODB2 code reader to
get the codes that way.
