did the BHJ install with underdrives and now the car hardly runs. any ideas as to what could be going on. when it does finally start, it runs very rough with plenty of black smoke, then stalls out. taking the the broken bal. out was, i far as i can see, the most difficult part of the job. putting the new parts on seemed easy. unless i'm missing something huge. any ideas?
