lately my car at idle will sometimes have a rough idle and then it dies on me and also when im cruzin on the highway at about 1400 to 1500 rpms it boggs really bad. i'm not sure exactly what it is yet could someone help me on this?!?!

 

It helps to know what year and what motor it has in it.
First thing I would do is put on a new fuel filter.

 

could be fuel filter, or pump?

 

Hmmm, could be something wrong with either the fuel or ignition systems. Might also be something in the engine.

 

i have a 88 iroc 350 tuned port pretty much stock

 

you ever try taking a look at the pvc valve?
