It was driving fine then with out warning i lost power and speed. Also it stalled every time i used brake, blinker or turned wheel. It sounded like it was missing so I unplugged the first spark plug and it didn't charge the way it was running. Neither does it change when third is unplugged. If i unplug the second or forth it stalls. I took the spark plug out and it gets a spark but I noticed it sparks without being grounded. I don't know if this means any thing. It still runs just like crap. no power.
