Please do not guess. But you might want to do a search on "O2 sensor" and find the values.

First, you must check for vacuum leaks around the manifold. Then check for any outstanding trouble codes. Clear any that you find and those that come back are a problem. Pull the spark plugs and clean them, check the center electrode for rounding because that means that you will need new plugs. Get OEM plugs for replacement.
Also check your coolant temp sensor. If the temp gauge on the dash is slow to go up to the middle, you might need a new T stat.
