Because of rough running, sluggish uptake I had the codes read ( it was time for the tune-up anyway) and they said I needed spark plugs, wires, distributor cap and rotor, and an O2 sensor was bad. I purchased all these but the man who read the codes forgot to tell me I could have a print-out of the readings so I don't know which sensor was bad. Now with everything except the sensor replaced the code reader only says that # 6 is misfiring...nothing about the sensor. The service engine light was staying on but now is only on intermittantly. It is still exhausting smoke smelling like gas. Is there a way to tell if the O2 sensors are bad and which ones? What can I do about the #6 misfiring? I really need a next step not involving taking it to the dealer. Just before all this starting happening the A/C compressor froze up and was replaced, the power steering pump bolt came out and had to be fixed then the hoses to it had to be replaced. There was a leak found in the radiator because I smelled a funny smell in the car. When I got it back from that repair it went back and they replaced the temp sensor.trying to fix the service engine soon light. HELP!
