Put the key in the ignition and turn it to the "on" position. Don't start car.

Now, turn it back to the "acc" position.

back to the "on" position.

back to the "acc" position

Now back to the "on" position.

Now look to the odometer for code information. Any code(s) will be displayed, followed by "-----" and "done" after the last code or if there are no codes set.

If you paid the dealer to fix the problem, they need to handle it. Take it back and tell them to fix it.

All I did was buy the part and had someone else put it in..... So what do I do now
"High airflow detected" may be because the new throttle body wasn't installed correctly. It may be leaking around the base. The first thing I'd do is remove it and make sure the "O" ring is in good shape and that it's installed correctly. You may have to get a new "O" ring.

i am going to bet that that it could be 3 things
1. o-ring is bad or gone
2. o-ring is missing from the egr tube on the back of the intake. someone at one time prob did a tune up with new plugs
3. there is a crack in the upper intake. from a tune up

all data list them as
1. intermittent dtc
2. vacuum leak
3. map sensor circuit (s) open, shorted or high resistance
4. throttle body circuit (s) open, shorted or high resistance
5. map sensor
6. throttle body
7. powertrain control module (pcm)

if you dont find or hear and hissing then here is a tip for you.
let the engine completely cool down.
make sure all of the intake is on
start the mag
very quickly spray some starting fluid around the intake (side by the tb, rear and under it.
if ther is any kind of crack. the the vacuum from the crack will suck in the starting fluid and the engine will rev up.
if there is anything else i can help you with give me a shout.
i have all data so i can send all the info that u will need to test everything.

when the TB is changed, its pretty easy for the IAT sensor plug and/or the O-ring gasket to not be 100% in place. double check the electrical connection, be sure that the gasket is on properly, and report back after that.

without being all proper with terminolgy here it is in barney rubble level as I said in the ARMY days LOL, what ever was removed was probably not replaced correctly and a leak of air is somewhere.
I would look for the proper placement of the upper intake plenum if it was removed (sometimes a bracket is missed and everything else seems to look fine)
Check all the air hoses attached to the upper plenum. the hoses may not be plugged in or even be frayed, split, hole, cut etc.
The metal tube hose in the back of the plenum is a BI**H to put on if you dont do it the right way.
Or you may just have the rubber ring around that metal tube back their behind the plenum all jacked up or ripped up like mine was i had to use silicon to prevent air from being sucked in.
Whatever I missed everyone else chimned in about already, damn tune ups always make me miss a step in puttng it all back together properly.

I'll bet it's at the seal between the throttle body and the manifold. Odds are that the "O" ring got pinched during the install or there's some debris that got trapped during installation.
