studder/wrx sound problem..PLEASE HELP!

[playastarkz123]

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?

Did you check the coils?

Did you check the coils?

sounds like you have a misfire check coil for spark change spark plugs and pop off the injector clips one by one if all else fails check the voltage going to the injectors that's where my problem was
