weird problem

[95talonracer]

How can you tell if it is running rich? (Wideband??)
Have you tested your ECU with another one? (may be bad but not visable)
Did you pressurize the air system? (Real boost leak tester)
What injectors and tuning method?
What gas and how old?
Your 02 sensor melting may of damaged the ecu with wires all touching and shorting out other areas of the ECU or wiring harness itself

could also be a bad maf if your still using one, or your o2 sensor is richening everything up by throwing a bad signal..
