i have a d15b in my 4 dr. i bought it swapped in there. the back mount is busted bad so the motro shakes the whole damn car. sometimes it would missfire while i was drivng and i thought nothing of it. then it started to just stop firing while i was driving and i would gradually slowdown until the car died. now the POS wont start. however it did start once but it suttered and i had to rev it to keep it alive. so i drove it and got to a stop and it died and wouldnt start again. its throwing a code 15 so im thinking there maybe a wire in my distributor that is loose. what do you think?

 

either test the wires or swap with known good distributor if possible. I had the same sort of problem with mine and it ended up being the distributor.
