    taking off cat converter

    I will try that. The car does run rich. When I ran the codes it gave my 31 and 83. Both EGR related if I remember. Any info on that would be helpful. Does anybody sell and off road exhaust for the 2.3 like they have for 5.0's

    taking off cat converter

    What would happen if I took off my cat convertor and put in just a straight pipe? My cat might be plugged. If it is could I do this? I have an 1989 mustang with a 2.3 that shuts off after 30 seconds starting. It restarts and then does the same thing.

    Problems with 2.3 staying running

    The timing is set correctly and I also changed the fuel filter. It still starts and runs for about 30 seconds then it acts like it just shuts off, like you turned off the key.

    Problems with 2.3 staying running

    I am new to this forum since this is my first 2.3. Problem is that the car starts and idles. If you put it in gear it dies, also if you let it idle long enough it will start shaking, sputter, cough and die. It also spit out like black carbon out the tail pipe. I have replaced plugs, wires, dist...
