check idle air control and make sure your battery ground is tight.

^^ This. If it is not properly adjusted or is malfunctioning the engine can surge or hunt for idle. How is your throttle cable adjustment? Was the T/B ported or altered?

The idle air wasn't adjusted correct fixed that problem how do you adjust the throttle cable we have a bit to much slack blade almost opens all the way but it's still only at about 90~95% open

i think it can be adjusted near the bracket that holds the cable near the tb

could be a vaccum leak, it happened to me.
Edit: Nm just read the OP. Not sure then

Surging idle is fixed just trying to figure out how to adjust the throttle cable. Thank you all for the responses
