Re: Engine misfire causing rough idle
from the dealer service department:
Cylinder #3 misfire detected. performed minor tune up and cleared the
codes. advised the customer that if the check engine light comes back
on the cyl head will need to be removed.
well after $112.88 last Friday, the engine service light did come on.
the cylinder head removal and fix will cost about $1,000..........
Advise?
Thanks

Re: Engine misfire causing rough idle
My first advise would be to find a 'real' mechanic, you are being took.
They basically put it on the computer and cleared the codes. For a
hundred bucks that's all you get.
'What' was included in a 'minor tune up'? What parts were replaced?
There are a ton of things that can cause a misfire. Usually spark
related like a bad coil connection or even fuel related like from a
dirty injector or even just a bad spark plug.
Some folks put Bosch spark plugs in. Most Jeep engines will develop a
miss very soon after, they just don't like those plugs.
It sounds like they want to sucker you for a valve job maybe which
'shouldn't' be needed on an engine with that low a miles.

Re: Engine misfire causing rough idle
Including the code that is set!
There a few TSB's out on the 2000 involving rough idle. These all imply
the computer programming is just plain bad and the computer needs new
software.
One is for bad idle after a hot start, another is after a cold (below
50F) start.

That data page might need to be drilled down for again..
