OK so i have had this problem for along while and im just sick and tired of it. I have an s13 sr20det, the problem is that when start the car its idles fine at about 1k but it sounds like its a wrx (studdering) it sounds like this when i drive too, all the time.

I did a test to see if it was my injectors one by one and taking notice of any changes in idle. Cylinder one had no change. so i replaced it ...same problem.

i have also changed the plugs, fuel filter (z32), checked grounds, vac, and boost leaks.

I dont loose boost but or idle low, jus this stupid studdering sound. Some times i get a more lean than normal afr reading from wideband also.

any ideas?
