Spits and sputters when you put it in gear and holding brake. clears up once your moving. will adjusting the idol help this
You are not supposed to adjust the idle, ever. that is the ECUs job.
adjusting it , now, means you have lied to the ECU.
it wont ever be right again. leave that screw alone, its a factory set
adjustement.
nice guess though, very carb like guess. Is common idea... sure...
its EFI. and has Idle speed controls.
if the engine misfires, (yours is) the RPM drops, the ECU tries to
raise idle 2 ways, by opening the ISC and advancing timing.(spark)
this can fail easy , if any EFI engine misfires.
what happens is the ISC has lost control..
lets use 1 example , 1 cylinder is dead, the ISC can NOT fix that. nor idle right.
the solution is to leave the idle alone.
and.
then fix misfire, than last fix the ISC functions.,
but i get ahead of myself......
Did you do the 60,000 mile full tune up as listed in the oper guide?
no? well misfire is going to happen. (new spark parts and filters)
tune it up. if still misfire. we diagnose that 2nd, and fix it.
there are tests for each step. I can show you them, all of them.
there are over 50 causes of misfire.
here is a great list. and is not complete. !!!

one common cause is a leaky EGR main valve
now that guy is very pesky , even stalling engine
every traffic stop.
SOURCE: acceleration problems.
see if all of the spark plug wires are attached, if so the replace the spark plugs, if not that then replace the spark plug wires, and last replace the distribution cap

If Engine Starts with accelerator pedal depressed , check idle speed control valve (if equipped) and wiring connection. Did you check for vacuum leaks. Do you know if your ignition timing is correct? How did you check your fuel pump? I take it no codes have been set, so if not there are several things to check for when the engine stalls #1 is to check cold start injector and cold start injector time switch. If engine stalls sometimes- check airflow meter and connectors You can tap the connector or relay or wiggle and notice if there is a slight change in the engine idle.

That means trouble with the manifold pressure sensor, which causes trouble with injection and ignition timing. See here p372
