Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.
Although may things can cause this issue,I would look at the items above first.
Please rate this a blue fixya

Poor acceleration would be from the misfiring, so start there. As Ruben said, do a code scan for trouble codes. Does it misfire all the time, or only under acceleration? Use insulated pliers and pull the plugwires off one at a time (and replace) until you find the misfire. The misfire will not change engine speed when removed, but a plug that is firing will slow the engine noticeably, maybe even stall it. When you find the misfire, it may be a bad sparkplug, bad plug wire, or the coil for that cylinder.
Be careful with the plug wires. Before you begin, loosen them from plug and reinstall, so they are easy to pull off when engine is running.

These are codes for misfires on #1,#2, and random cylinders.
A cylinder will also misfire from the injectors as well as the spark side. If this is a v-6, check for camshaft position sensors.

A P0300 diagnostic code indicates a "random" or "multiple" misfire.
Unfortunately, P0300 doesn't tell you specifically which cylinders are mis-firing, nor why (code P0301 would indicate cylinder #1; P0302 would indicate cylinder # 2 etc). This means there could be an issue with any number of components/circuits relating to the ignition/combustion circuits.
I would recommend you check for the following:
Sometimes the underlying cause of a random misfire is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold, unmetered air getting past the airflow sensor, or even an EGR valve which is stuck open.
Hope this helps...
