After I swapped my edelbrock Victor x IM for a Skunk2 my idle started acting wacky. It idles at about 1500, and after I blip the gas a little bit, the rpms will drop down to 800-900 then immediately jump back up to 1500. Does anyone have any ideas?

 

could be some kind of gasket or vaccum leak.

 

vacuum leak. definitely.

 

the car hesitates really badly when I drive it too.. like if I just barely depress the throttle pedal the car wants to jerk back and forth till i give it more throttle..

 

vacuum leak..

 

thanks i'll go look at it

 

Spray carb cleaner all around where the leak could be. When the idle jumps, you've found your leak location.

 

i dont think its vaccum...try ur fast idle..take it off inside should b a plastic screw..tighten it all the way that should fix it..
