got a 420 that cranks idles fine, when you give it gas it acts like its bogged down?starving for fule.
Changed fuel pump..fuel injector, found sum wires that looked chewed. Fixed them. Tried changing the computer board..because of anti theft it wouldn't even start. So put mine back on what yall think is wrong with it tiny bug just cant figure it out.

Hello,

Was this Rancher stored for a long time with fuel left in it? If so, you'll have to flush the tank & clean the petcock & replace fuel filter. If not, tell us some more about those chewed wires... where are they/what do they connect to?

Welcome to the forums!

Welcome to the board..

Anti theft?

When you say it bogs down...does it cut out like a rev limiter? If you have a brake handle pulled partially back and start it it will cut out like that. I doubt that's your issue but start with simple stuff first.
