sliver280

ok i figured it out and figured all should know the problem was in the throttle positioning sensor had water in the connection

Can anyone help here just got my z running been 20 yrs since last time motor starts ands idles great but cant get the rpms up above 3000.rpms hit 3000 then drop to 2500 and back up to 3000 its not spark because i hooked up a tester and the sparks never stop even as the motor goes down to 2500 so i figure its fuel but where to i start?
