Hey deserttracker, thankyou for your response, I have not had time to look at the problem but I will take your advice, I have already changed the o2 sensor and replaced the plugs and coil, the wires cap and rotor are in good shape. Now unfortunately I took it to a repair shop, which mind you is a first for me, I got the tracker back in worse shape than it was. Now not only is the fuel still coming out the exhaust, the rpm is running at 2300 on cold start and 1500 at warm up, I don't know what this shop did but I am going to find out and get the idle back to normal, I am also leaning towards the #3 fuel injector because the shop did tell me that it is not functioning properly. Again thankyou for your input and I will post again any results that I may find.
