I added a cam and longtubes to my car, 98 trans, idles like crap, cant afford to get it tuned right now.... so is there anything i can do on my own to make the car idle better? it needs to come up some? and im not scared to mess with the computer myself so any help would be preciated

 

Sometimes just opening up the throttle blade is a little bit of help. But depending on the size of your cam, a tune is needed.

Crack the throttle a touch, but the "right" way to do it is raise the idle speed in the PCM.
