Intermittant poswer loss
 

1988 RX7 convertible
losing power occasionally when accelerating....also , when I put it in gear (any gear) the rpms drop off and sounds like it's missing...wonder what the neutral switch does in the ecu?
wondering if it's gas related, as I had switched stations just before this started happening... switched again and the problem has lessened but still there..
also, changed the spark plugs and the front rotors plug showed wear, but the back rotor had very little wear and oily...
