I recently purchased a 01 eclipse rs from a private dealer. About a week ago i decided to throw in an aem cai. I used the same MAF, and it sits exactly where it did on the stock intake. As soon as i put it on, my car would bog when i tried to accelerate. It appears to be missing firing and i had the computer check the code. Came up P0300, a random misfire. Now it doesnt happen everytime i accelerate, just off and on. I have put new cheap spark plugs in, but plan to get a set of ngk's in a few days, but ive got the feeling it wont solve my bog problem. Any ideas?

 

i dont see how the intake could be causing that. It must be something else. The spark plugs probably wont do it if you still have new ones in there, maybe change the wires.

 

might have gotten a foreign object inside your intake while you were installing it, and it got in your engine

 

This problem code can be caused by a vacuum leak in the intake manifold, throttle body, vacuum plumbing, or it could be unmetered air entering the intake manifold (MAF sensor). If you don't figure out the problem I would install the old intake and this will tell you if the cause is your intake. Also double-check your hoses and make sure they're all hooked up correctly. I highly doubt you got anything in your engine!!

 

vacuume problem like XTREME said cuz thats what happend to me so make sure its sealed up and **** and u should be good.
