so i put the car back together and started it and i heard a nocken noise i found out no oil was in it i dont know how it all drained out but i put oil back in it and it nocked for a little while longer then it stopped.....it hasnt done it since should i be worride..........another thing is i drove it home in the rain last year without out a hood...cuz i was racing in all..and a rain storm got me on the way home but anway since then it misses really bad till u get on then i clears itself out i have no idea why it does this...at idle it sounds horrible
not sure if you checked water under the cap? try to dry it and spray some wd40 init . always worked out at the mud hole for me .
