when i run my car it starts to sputter a lot when my rpms are high. does anyone know what this could be.
please help me.

 

welcome to the club i have the same problem and have been chasing it for months i am pulling my hair out!!

 

On topic: It could be a list of things, or just one thing. What have you replaced so far? Do ALL general maintenance first which would be:

Plugs
Wires
PCV
Fuel Filter
Oil
Oil filter
Air filter
Flush coolant system
Edit: coil
Now thats out of the way, it's probably your egr. Good luck.

Off topic: A v6 with z28 badges... Why?

What about your coil? Damn 2 questions in a row i answered with that. But its the one thing people arent listing that they checked.

$35 gets you a new coil as well

If not what about the fuel filter?
