mpfi swap problems...
so i swapped my lil dx to mpfi as i have a ls vtec waiting for it so had to do it anyways...im having a couple problems though...the car starts up and idles real poor...idle is all over the place....also when i have the key turned to ignition not started theres a hissing sound coming from either the injectors or something fuel related...its right around the manifold...i know its not a vacuum leak cuz the car isnt on....the car is giving codes 43 which is fuel supply, 9, 1, and 14,...i swapped out the idle air control and nothing...i switched the wires on the dizzy to see if i had gotten them mixed up and still code 9 is there...im guessing the dizzy is bad but the hissing and the idle has me going crazy....and when the car is on it runs super rich i can smell it...do u think a injector is staying open???...could that be hissing...im off tomorrow so ill keep on going at it but i can think of what else that hissing or idle could be related too...let me know guys...thanks...

Re: mpfi swap problems... (e jay one)
so are you just putting the mpfi manifold on your dx engine? or are you putting in the ls engine???? if its the dx engine.. how the hell did you get a code 43? figure out exactally where the hissing noise is coming from.. cant really help you if you just say theres a hissing noise.
