Just got Tracker fixed things I went thru before found problem. I replaced the Injectors, Replaced the ECM, Replaced the 02 sensor, Replaced the MAF sensor and other sensor on the air cleaner box, This was after I took to dealer and had put on computer to check for problem Computer only gave a running rich code, replaced the injector relay, checked the cam sensor in the distributor. Still same problem existed - I used a screw driver like a stethoscope and found #1 & #3 injector was not clicking like they should or like #2 & #4 was. Checked wiring harness every where I could. Ended up unbolting the motor mount on right side of engine pried it away from engine to check harness there found two wires that had insulation rubbed thru to bare wire and were grounding on the engine which kept the injector locked open and flooding the engine, oh yes they were the color coded wires that sent ground to injector #1 & #3. I was at the calling it quits point for my expertise but hate having my butt handed to me. I want to thank everyone that tried to help and I do know that any of the recommendation could of been the problem. I hope this response will help someone else that has the same problem.
