acceleration problems

I have an 04 alero 4 cyl. When I attempt to accelerate it takes forever to pick up speed. Sounds like a gas guzzling truck. Sometimes the rpm will rev up but car is struggling to pick up speed. Ive had the transmission checked, no problem there. Any suggestions

could be an ignition coil problem. possible your cylinders aren't hitting right

A misfire would trigger the check engine light.
Possibly a clogged catalytic converter. You might also check the fuel filter and fuel pump. If the filter hasn't been changed in a while, just change it. It's a $10 part at Walmart, and a 15 minute job in your driveway.
