ConfusedMy son has a 2001 HOnda Passport that has a nasty habit of running real rough every once in a while.  The check engine light used to come on but no longer does when the engine decides to do its thing.  It sometimes does not like to idle and then when started will be real rough running on acceleration but smooth out when at speed and not under pull.  Back when the check engine light would come on there were too many codes for the Auto Zone tech to decipher what was happening. 
We changed the plugs, fuel filter and air filter and that seemed to take care of the problem for a little while, but lately it has started occurring again.  Any ideas on what to do?Confused

Confused[/QUOTE]

Take it back and have them pull the codes, and ask them to not try to decipher them, just print them out...
The codes will help determine a starting point. Get the codes(if any) and post them here, or you can P/M me, and we'll "decipher" them ourselves...
When you changed the plugs, how were the wires?
There are a LOT of things that can cause this, and Ken might have better insight on narrowing down the trouble, but codes will certainly help...

Can't get the codes -- the tech (?) cleared them out when he read and the car has not registered anymore codes.  However, it still on occasion does the bucking on acceleration and dying at a stoplight. 
 
The plug wires were good when the plugs were changed.

Wow...so many things can cause it...where to start?
Without the codes, or data info, I can only guess.
Could be:
Temp Sensor
MAP sensor
Ign. Coil/Crank sensor issue
TPS(throttle position sensor)
EGR malfunction(Honda has had a TON of troubles with their EGR systems)
Injector wiring(as the engine moves under load, it stresses the wiring harness)
Alternator problem(yep...it's computer controlled, and a malfunction in that system can skew reference voltages to any/all of the engine sensor).

Kinda flyin blind here!
I'll check tomorrow for any TSBs from Honda, and see if I can come up with something to narrow down the possibilities...no guarantees, but I'll see what I can find.

Unfortunately my system has been acting up and finally crashed.  We are back on line for a little while -- the laptop is working hard at trying to provide services.  Anyway -- I did not get your email, can you resend?
 
Thanks

It's back but this time we got the codes --PO172 and P0171.  I pulled the MAF sensor and cleaned but no improvement.  Any ideas are welcome.

Well, now we're gettin somewhere...let's jump up on da sidewalk and take a look. Those appear to be O2 sensor codes, but I'm not sure. I'll check once I get to the shop...stay tuned....
