great question, why not use a real scan tool and scan it
the tools is like $10 (ask)
when cold and damp all bad high voltage ignition system fail.
from the tin lizzy 1920s to 2015, (for the same REASON)
but today the scan tool helps you with that.
my guess the car has never been turned up this decade.? like most here?
FAIL EMISSIONS, sure, if the CEL glows running you FAIL.
in every state in USA, you fail; (this is a USA forum)
2003 wrangler with the 2.5L or what engine? 4.0L I-6 (inline 6 banger)
not posting engine and the talking smog is a hopeless to all but
i can wax , physics and laws or Otto Cycle , generic.
the engine will fail smog for many reasons, Ill ;list some.
top fails.
- Engine misfires, (50 causes ) top cause bad spark. not ever tuned up. with spark plugs and wires, (P03xx codes)
- EVAP , failure, more DTC error codes, scan it.?
- Transmission errors (P07xx codes)
- Lazy CAT P042x codes.
- dead O2 sensors (any) for any reasons.
- lots more, but why must i list them if you can just scan it.
post back with facts and we can go as deep down the rabbit hole
and take the red pill (complexity path)
hints
if engine has COPS get new boots,.with spark plugs
if engine has a 4 wire coil pack, get new wires, and dont mix them.
remove 1 by 1. not mixed.
cops are engines with DIS that use, COIL OVER PLUGS>
the boots are cheap the cops not.
so boots we do, (savvy) first.
