Do you have a check engine light on also?

These engines are bad about jumping time.

check engine light is on also. it also makes a loud suction noise when i hit the gas witch sounds way to loud for stock intake. could it be the pcv valve?
Expert:  Jared D replied 1 year ago.

It could be. It could also be a tear in the air filter ducting. I have seen these ducts get brittle and tear when the engine flexes enough. I have also seen them pop off and cause a stall condition. Have you inspected the ducting for air leaks? If you can get someone to keep the engine running by pressing the gas while you listen for the source of the suction noise it's much easier.
