Well i just installed the intake and i wired in the whole ecu. Took her for a ride and check engine light came on. Also the trac off/snow lights came on too. The paper that came with the intake had pictures of the ecu. One was 2001+ and one was just 2002. Mine being an 04' i used the 2001+, so when i was driving it at neutral warming it up it sounded like it was going to die. At one point it really stunk bad. I followed the instructions but it didnt match exactly with the locations. The colors did though so I followed them. I hope someone can help me!!! I am going to call the number but I cant right now being that it is a sunday so any help would be GREATLY appreciated!!
