Okay, well its texas and it has been below freezing the past week or so and i installed the new sct chip and re positioned the maf and a couple days later i started her up and the idle seemed fine for a second then it got realy rough and bouncy and started to drop below 500 and i could here it trying to stay alive so i turned it off turned it back on still rough idle around 750rpm but it seemed fine? It seems to do this the last 3 times i've started my car? I just rev it a bit, is it just because its freezing cold outside lol and the engine is cold? Have not noticed this before but then again it doesnt get to cold in texas like it is now! Anyone else have this problem, could my MAF be leaking out a bit since i drilled some new holes to re position it?
Rough idle, drop in rpms? What causes this?

What made you change the position of the MAF? That can throw off the a/f. Did you have a dyno tune done?
Was told it needed to go back to stock position at 10 o clock rather then 12 where it was after putting on the FIPK in order for the a/f to be right with the tunetorquefreak said:
Most are set to the 12 position with the k&n Fipk, Mine included. I have a dyno tune done for that position so no problems. Might be a leak you need to check for as you mentioned.
Sounds like some kind of leak. Check around the MAF and around the TB. Sometimes that comes loose.

Try resetting the computer. Disconnect the battery for a while then reconnect.
Hey, how will i know if its leaking? how do i fix it? Can i slap some silicon on there?SA SNAKE said:

the above makes since so does a leak...isn't the FIPK designed to run the MAF at 12? does it run like shit at 12o'clock? I tend to feel that the stock position is best...but that is my opinion

Get a can of quick start and spray it around the area you suspect there may be a leak. See if it the idle changes. If it changes you have a leak where you're spraying.
