I have an 89 Lx 5.0 pretty much stock. Car wants to die when it reaches half a tank of feul and after, but only does it during a right hand turn? Any ideas?

 

Most likely the baffle in the tank has come loose and is moving around and interfering w/ the pump. Very common problem. If this is the case, you'll need a new tank. You'll need to pull the tank to be able to verify this

 

drop the tank and look inside for a broken baffle as PRO50SC states

 

ok, Thanks!
