Best Answer

Pluged air filter, oxygen sensor is bad, bad catlitic converter. A tune up can help. Use the cheap gas it has less hydrocarbons in it Check the EGR valve. It might be plugged up with carbon. The EGR valve allows exhaust gas to be recirculated back into the engine and if it is plugged up, this doesn't happen. The EGR valve is to control the NOx emissions.
