Engine running poorly

[mrnapolean1]

It ran very bad before a full tuneup but now it runs better but it does not idle.
Also it sounds like its spitting (sometimes) when the gas pedal is pressed.

If you let off the gas pedal it will sputter and die.

Fuel pump/tank/filter is brand new as well as all 8 spark plugs/wires/cap/rotor

It sounds like you have a vacuum leak. Not sure what motor you have, but the easiest way is to spray water around the intake area. once the vacuum leak is found it will start to choke out. Sine it won't idle, it has to be a pretty big leak.

The hose going from the throttle body to the PCV Valve was broken so I put a peice of rubber hose and made a sweeping bend. that was the only thing I could see that stuck out.

BTW I have a 350 V8.
