collapsed cats?
blocked fuel filter? Air filter? fuel pump starting to die. could be a number of things. have you swapped back to the original coils to test if the MSD's are faulty? Assuming it was running fine before. If you have only changed 2 things being coils and leads and it was fine before, one of those 2 things is not working properly. basic deduction. |

Put new plugs in it, if the plugs are worn the extra voltage from the MSD's can finish them off.
