   Both answers are right. It could be a number of things causing this- all of which can cause emissions-related issues. Have you had that car tuned up? ignition and timing issues are easy to fix and can cause your symptoms and tha check engine light. Many mechanics will disagree but I know from experience that sometimes just a tuneup could be the problem. I’m not saying that the answer to all of your problems but don’t dismiss it either. Replacing spark plugs, wires, air filters might solve your problem. If you still have the issue, consider the distributor cap and/ or fuel system service. Others could be more serious: dirty or damaged EGR valve, throttle body, catalytic converter, bad O2 sensor(s), etc. Get that car check out by a mechanic.

   My guess would be something emissions related.
