Hi I have a 93 miata, so the 1.6l, and the other day I was drifting in the snow. I went to pull the handbrake not remembering I was in second gear and the car stalled. I tried to start it and it starts but then dies about a second later. I can also get it to idle if I turn on the a/c and it sounds to me like a vacuum leak or a misfire. Could a bad spark plug cause it to do this? Because I know I need new spark plugs
