Don't diss being a girl, at least you ask around when someone starts
feeding you a line of BS!!!

Your symptoms and error code are signs of a vacumn or manifold system
leak somewhere. Other folks mentioned the Mass Air Flow sensor, this
shuold be checked since it's easy to get at but I doubt it is the
problem. It is really just to fine tune the engine, not run the basic
air mix.

Lean mix codes usually mean change out the O2 sensors, there are 3 of
them, 1 on each exhaust bank, one on the output of the catalytic
converter. Your error codes are the result of one or the other of the O2
sensors on the exhaust banks saying the engine is too lean, engine
computer cannot compensate enough to get it rich again. Since you get
both banks, I doubt if it is the O2 sensors.

Assuming you have the standard 4.0 V-6, these engines are prone to
warpage and leaking of the intake manifold to the block. Symptoms are
the two error codes you are getting , radnom codes of both bank 1 and
bank 2 too lean. Other symptoms are hesitation and bucking at low
speeds, poor cold idle.

You need to have a ****GOOD**** ****DEALER*** tech do a full diagnostic
on the engine. The clerk at the autozone place does not qualify. Show up
at the dealer, tell them you have a nagging and recurring problem, do
they have a top engine tech that can look at it. If they don't
immediately say "well, that means we need to have xx or yy look at it,
xx is booked until next week, yy is booked until Friday, can you wait?"
go somewhere else. Top techs get booked well in advance.

If it is the manifold gakets, plan on $500. $130 for the diagnosis, $100
for various gaskets and other parts, $300 for labor. It's fairly
involved to dig all the way down to the offending gasket.

Cheers.

To run the basic air mix, the most important thing the computer must
do is calculate how much air is being taken in, so it can determine
how much fuel it's gonna take to make the engine run. That is what the
MAF sensor does. The modifiers would be temp (air & coolant) & baro
sensors with O2 sensors for fine tuning.

Uhh... Lean mix codes USUALLY mean the mixture is lean, NOT to throw
an O2 sensor at it.

To run the basic air mix, the most important thing the computer must
do is calculate how much air is being taken in, so it can determine
how much fuel it's gonna take to make the engine run. That is what the
MAF sensor does. The modifiers would be temp (air & coolant) & baro
sensors with O2 sensors for fine tuning.
