Im misfiring bad, I replaced cap, rotor, plugs, wires and YES, its still misfiring. While running i pull #1 off no engine change. i pull #2 off no change until i go to put it back on and engine revs up a little for a second or two. #3 and 4 seems to be ding its job. Can this be a timing problem? The car was running fine, then after it set for about 6 hours while i was at work, when i went to start it, I caught hell getting it started and then this misfiring was there, i was only running off off #3 and 4 cylinder......a code came back that the gas temperture sensor was bad, hmmmmmm? can that b a problem? I could use some help and would like to thank someone in advance.
