so im sitting in a mall parking lot listening to music. Then when Im about to start it up (didnt get to start it, still in accesory mode) it starts knocking (loud knocking) a couple times, i turned the key left and back into accesory mode and it still knocked. it did it a couple times then stopped. I drove it home no problem after that. btw its an 89 accord carburated. :thumbdn: :huh: :wtf:
