Errors E-23, E-30, E-31 and E-34,

Hello I have a Caterpillar Forklift Model P6000 Serial AT13F00463 I have the following error code E-23, E-30, E-31 and E-34, E-31 is intermittent.
Any help would be greatly appreciated
Online says
E-23 is throttle sensor error circuit.
E-30 is a ECU error signal
E-31 electronic throttle control system error
E-34 is a spark system error signal.
All of the cylinders drop RPM when I disconnect the coil.

I make them pick things up, and I make them put things down, and I make them drive around.

"Unicarriers - it would have to be for a dual fuel unit also. Usually a bad cam or crankshaft sensor will throw a E-27 or a E-28 code on the dash panel... If it does not light up and the bulb is bad then it will not start also."
