Nope, it does it at any level of gas.

 

Fuel sync won't have anything to do with that. Sounds like you are either losing fuel, or spark on 'hard' corners. Might just be a bad connection somewhere.

 

Well my auto teacher says his two dodges did it too and one was a 2011 5.7 and a 2013 5.7 so I'm not sure what to think.....another issue is when im at a stop and take off my truck seems like the transmission is slipping. I lost a quart- quart and a half of fluid when my dipstick was ripped out but I checked the level and it said good. The first stop after I start my truck the rpms go down to 300-400 and then come back up to idle. Then I take off and it dips down 250-300 rpms then flares up 500-650, is it my trans or something with my motor? I'll try to get a video of it if I can. I also set my fuel sync to 0-2 so that's good.

 

May just be re-learning the IAC, or, the IAC may be getting old and slow. Some of the aftermarket fellers just aren't what they should be either..... (idle issues)

Go looking for any possible vacuum leaks. Also check TV cable adjustment.

 

How much is a new IAC? And for the TV cable, are the specs in a Chilton's manual or FSM?

 

you could take the IAC off and clean it (gently)

tv adjustment should be in fsm

 

My IAC is cleaned up though. I tried to not move it at all when I was cleaning it.

 

is it the original IAC?

 

No its the IAC from my 318

 

Can you make a video of it happening, and you should just buy a new iac they aren't too expensive.
