I have a 1990 corrado g60 and when i rev the engine up as it goes back to regular idell it either shuts off or it putts like its going to cut off what could this be?

Does it sound like its going to splutter and die? ISV?

well it doesn't sputter too much but yes it will idell real low and shut of unless i press on the gas and sumtimes it will save its self. and when I am just sitting idelling sometimes it idells alittle high but not too bad

how does it drive, stuttery? slow on full throttle?

 

any work been done recently around the fuel rail?

 

blue temp sender worth changing if it hasnt been done recently.
