Alright so I have a Suzuki samurai with the 2.0 lsj out of a 2006 Chevy cobalt ss, and I'm having some weird issues with the throttle.. I will start up the motor and drive down the street and randomly while just cruising at any speed the throttle input on my end will cut out and will just go straight to idle.. The motor doesn't stall at all or anything it just goes to where as if j wasn't putting and movement on the peddle and let off the gas. So I will then stop on the side of the road put it in park shut off the engine wait a minute or two and start t back up and throttle will respond perfectly fine no problems.. Now if it happens again after that is totally random and there have been days where it doesn't happen at all and there are days where it will happen more than 3 times in a row. I'm also getting codes thrown out

Hoping someone on this forum has any answer to this problem and would be able to help me out, I do not want to shotgun maintenance this thing and throw parts at it and not solve the issue and thought this would be a good place to start thankyou everyone!

 

Did you search/google those fault codes?? (all throttle fault codes...)

Clearly something wrong with your throttle wiring, so start there. (pedal> connectors > ecm > connectors > Throttle...)
If the ecm detecs a small error in the pedal voltages due to a bad connection it will immediately go into safe mode.

 

I'm no help but I wanna see some pics from her build.

 

An lsj swapped into a samurai and converted to auto? Pics and more information are definitely needed

 

I will post pics once I'm off work.
Yes it has a Chevy turbo 350 trans, I'll take pics of it and then pics of thewiring and connectors
