Well check this out. Do any of you remember when I had that problem when I swapped that JDM D15B into the DX? Well anyway, it would start but it ran like crap and then would die if I pressed the gas, I checked everything you could think of. Finally we had it towed to a shop and one of the brand new spark plug wires was faulty. that is all it was. Also, check your firing order. Had I known more about testing electrical components Iwould have caught it.
