Three things needed for an internal combustion engine, fuel, spark and compression. Is the fuel contaminated? Are the injectors being driven correctly, or are they "on" all the time? A wiring issue can be to blame. The injectors are powered all the time and pulsed by the DME, if the wiring harness is shorted internally, the fuel wont stop flowing through the injector. If the CTS is faulty it will tell the DME to run full rich. If there is spark, is it getting to the cylinders? What is the mechanical condition of the engine? Does it need a valve adjustment or perhaps a bit of valve work? Unfortunately, I cannot see what you are seeing at the car and my involvement is somewhat after the fact. I resist giving advice regarding replacement of parts due to the fact that that may not solve the problem and that methodical testing, if followed, will inevitably uncover the root cause, then replacement of parts can easily be justified. I recommend that a check list be generated to state what is so, start with the basics as referenced above and in the past threads, and let me know what you come up with.
