I say take a look at the spark plugs you installed if it was after putting those in. Take a look at your spark wires too. Maybe have a look at the idle control. Reseting your ECU is a good idea if you have an aftermarket intake. I wouldnt bother waiting 10 or so mins just pump the brake and that will use all power in the system. Look before your MAS for a leak or a hole.

 

a leak before the MAS wont make the idle jump a leak after will. If it leaks before the MAS then it never gets counted to begin with but if it gets counted and leaks out that would be different. unless the MAS isnt getting barley any air.

I say check the TB flange EBay intake will crack it if that is what you have

 

i don't have an aftermarket intake. it is still the stock intake but i will check out the possible problems you mentioned. thank you.
