Drove the car hard a few times but never had a problem until last weekend. My car idles at 1200 rpm when it gets hot but now when I put it in gear the idle drops real bad and some times stall. Now wut is going on with it.
It is an automatic and my mods are cool air intake, underpulley ,3 1/2" dp and exhaust ,no precats . Need help to fix it cause I am just getting tired of all the problems I'm getting with it.

 

Does anybody have a clue on wut is wrong? Please help. A friend told me to check for a vacuum leak, could this be?

 

My car's idle always keep @1500rpm. After replace the lower intake gasket. Its idling fine. Check it
