I had the same problem recently, but gave me 2 codes knock sensor (which will not activate the service light as i found around)
and gave me the air flow mass sensor. took it out clean it,
change the air filter,with a good one, vacum the inside of the filter holder and light went of about 2 days later.

this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.

Could be any one, or more, of the following -

Plugged injector
Bad plug wire
Fouled plug
Crossed plug wires (hard to tell sometimes on V-8s that run smooth anyway)
Vacuum leak
Leaky EGR valve
Shifted timing sensor

Scan engine for codes and proceed from there.

There is a product called RXP (available here in Texas) that will clean up an engine and gas. Its pretty awesome stuff, and this coming from a person who doesn't really believe in additives.

Do you have a check engine light with this?
What can happen is a code has caused the engine to protect itself. For example in a low coolant situation when the engine heats up too much, the engine can Knock causing an Engine Knock fault.
If that occurs you will recieve a fault for each of these items. Fill the engine with coolant. Then reseting the code will let your engine accelerate normally.

Battery not charging well when airconditioner on ( also engine speed not increase when air conditioner on )
