On my '05, I simply press the odometer reset button, then turn the key
on, then release the odometer reset button. The codes you get this way
will be limited, but it's better than nothing. That $90 you spent for a
dealership diagnostic would probably have been better spent on a good
code scanner for your toolchest. I think every vehicle owner should
have one, even if they never turn a wrench.

If the plugs have 2k on them and they're Champions, they're fine; so is
the fuel system. That fancy 'cleaning' consists of a $3.00 bottle of
injector cleaner poured into the fuel tank...that's it. Dealerships
should be ashamed of the way they treat customers.

My suggestion to you: were I standing in your shoes (and I have), I
would spend the $200 for a decent code scanner (not a code reader - big
difference), and stand ready to read what the computer has to say.
After you have that information, you can proceed to repair the problem.
Yes, another $200 for tools seems excessive, but you will use it many,
many times, and it's good for all OBD-II vehicles, not just your Jeep.

Something tells me that your dealership HAD the codes, but chose not to
diagnose properly to add profits. I have seen this before. They'll
offer you a 'discount' if it happens again for another diagnostic
($10-off or some other nonsense), and only after they've taken hundreds
in profits, will they magically FIND the problem; then it's another $xxx
dollars to begin repairs, which will be equally inflated.

$150 to unscrew 6 plugs and replace with new ones costing a couple of quid a
throw ?
I'd ask them why it takes them that long and offer to do a training course
to aid their productivity.
