ok i think it might be my maf sensor, has any one had this problem with putting a cold air intake on? and can i use the maf from the rb motor since it is so much bigger?

Try cleaning the MAF with brake parts, electrical cleaner, or alcohol.

Sometimes over oiled filters will get oil on the sensor.Another common problem is a bad ground on the MAF. Usually just adding an additional ground will solve it.

I had a similar problem with mine, try pulling plugs of the injectors. If it doesnt idle any lower when you pull one its more than likely a bad injector.

i just pulled one injector at a time, and when i pulled each one, you can tell that all of them are on and working, do you think it can be electircal? im going to try and add an extra ground tomorrow when the rain stops hopefully that will do something

lol, your maf is the sensor in between the air box and your intake pipe you cant miss it, it has a wiring clip on it you'll have to pull up the little metal clip, i used a flat head to pop it off, use crc mas air flow cleaner they have it at any parts store.
