cam install question

i put the hotcam kit in and now every once in awhile my car will die when i first start it and come to a stop under normal braking at idle. its like it stalls out because there isnt enough vaccuum. a friend of mine said that you can drill out a part on your throttle body or something like that and it will fix the problem does anybody have a clue what hes talking about and if so can you send me the link with instructions and pictures or something. thanks

My car did that before I had it tuned. Did you get it tuned yet?

I had the same problem and the same tuning. Only thing is I have a much bigger cam and a BBK TB (some say these are junk). I have already drilled the hole your asking about and it didn't work. If you want to try it, you take off the TB and remove the bottom part and drill out the hole in the bottom of the TB. I would check all your sensors 1st and check your voltage at idle to see if it's correct. I'm thinking about getting a dyno tune and dumping the pcmforless tuning.
