The year, make, model and engine info would help but in general it could be a vacuum leak or time for a tune up.

What causes backfiring in Kawasaki 220 bayou?
I have a problem. I just bought a used 1995 Kawasaki 220 Bayou. The engine started running a little rough at first. Kept getting worse and then started backfiring through the exhaust. I had the carbeurator rebuilt but still runs rough and backfires. Cranks good and idles good. What could be my problem? Thanks
What does system too lean mean on a 2003 Chevy silverado?
It means the Fuel/Air mixture is not correct. Too lean means the mixture has too much air and not enough fuel. If the engine idles rough but runs good under acceleration, suspect a leaking vacuum hose. If the engine runs perfectly suspect a defective MAF sensor.
What causes a squeal in the engine on a 1999 Chevy Corvette to increase with acceleration?
I have a 99 and had a nasty squeal that would be intermittant upon acceleration, I changed the belts (upper and lower) and used Gatorbacks (belts by Goodyear), and the squeal is gone.. Don't know if this is the problem or not, but it will only cost you about 50 bucks and hour worth of your time to find out. Good luck!
What causes rough idling?
There can be many causes of a rough idle. But if the engine runs good under acceleration and then idles rough, there are 2 things I would look at. First look to see if you have a vacuum hose disconnected, broken, or cracked. Secondly depending on the make and model, check the EGR valve. This is just the main 2 causes as there are more. -also rotor and distributor cap arcing - use only original dealer parts -O2 sensor slow - if it is old replace -ignition wires old or incorrectly routed -if gas smell do a fuel pressure leak-down test - should hold 50psi for 10 mins or more. May be pressure regulator or line leaking or bad fuel pump
