09 Wrangler Unlimited Cylinder #2 misfire
huh what is etc? is it hard to type facts for free expert help>???
09 JK , I own a 08, stick. 3.8L V6. right?
you never said mileage, why?, mines at 60k,
P0302, is that hard to say , that it one only just 1 code,and
you reset it, and it COMES BACK, you never said so...
(to reset it push reset on the scan tool)
or learn which fuse to pull, I have real FSM in hand. can answer that. (its marked OID) in the TIPM fuse box, pull m3 fuse
for say 5minutes, all codes are forgotten now. 3.8L JK
that (my had to guess) code means, this.
weak combustion on #2 only. (slow piston acceleration is a fact)
so if all 5 others burn right how can just #2 fail only.
ANSWERS:
well its NOT FUEL MIX is it.
leaving only these.
1: sparkplugs gapped wrong, did you set them or guess?
to SPEC<, is the answer.
2: spark plug wire #2 to coil pack lug 2, is this new?
we work cheap to expensive ok./?
3: weak compression on #2. check that WOT?
wide open throttle (about) but never at idle position.
4: injector issues. #2 only (swap injector or learn how to do balance tests and leak down test on them, out of BOOKs
not internet bs rumors.
there it is...
the order above is by complexity and cost.
throw in bad coil but no miles stated so ,i guess low?
do not mix coil wires, or it will misfire. it has only 1 way to do it.
