Map Sensor Whack

well, here is an update...
I had this TSB done, and thought it was working the first day (installed Saturday Jan. 8). On my commute Monday morning, and the same damn problem. Stop at a stop light, RPM drops and the whole car is shaking and shuttering. I wonder what is causing this? Anyone think a Valve Job would help? It is a 2003 with 23,000 miles. Spark plugs?

if you have the map sensor problem (intermittent hesitation under hard acceleration), is it obvious? i don't think it's ever happend to my, and i'm pretty sensitive to those sorts of things. but i hear about it a lot so i thought i'd ask those who have.
but i have had the idle problem, mostly in traffic. doesn't matter if it's hot or cold out, if i sit still or move < 15 mph for awhile, the car will buck when i hit the gas. only cure is to push the clutch, let it rev, then it's ok. fyi, the engine compartment is bone stock.

Do you guys know where I can find substantial information on this MAP sensor thing to prove to my dealership that this is warranty work.
xviper, any ideas? This has not fixed my problem. It is sporadic, and seems to be triggered by humidity (Houston, can you believe it
.
Could it be a grounding problem? Valves? I am really stumpped. I just hate going to the dealership because they usually don't know or break something else.

If you think you have had a MAP issue, Honda might perform this TBS for you. I say might, because TechServBulls are not a recall and each dealer is different. Proof (a dealer rep driving your car HARD) may be needed to get this TBS done. If the dealer feels your engine hesitating at high rpm they may choose to perform this TBS under warranty or as a good will gesture. They may not. They might have just busted up your car and refuse to fix it claiming owner abuse.
If you don't want to go through all the trouble, just buy one or a couple of the Tie Wrap: P/N 32125-PCX-003, H/C 7868607s for $6.47, slide it into position, zip it and forget it. Or use one of the other backyard, ghetto methods posted.
Why are they replacing the MAP sensor with this TBS if vibration is causing the contacts to loose material and conductivity, thus changing resistance? Would not the connector contacts wear away the same material? Or are the MAP contacts the sacrificial contacts? I would think an improved connector would be the true fix. Although if a $6.47 piece of plastic will do the trick, I'll spend it, for piece of mind.
May I also suggest that prior to installing the tie wrap, remove the connector, clean (with an electrical contact cleaner) and inspect the condition of the connector and MAP contacts?
I'm not touching the old Bucking issue with a ten foot Tie-Tie.
