So i finally got my car running after it sat for 6months.Due to having a short that took me forever to find.It ended up being that it was shorting

out from the coil harness .I fixed that,proceed to turn it on and it idle ruff/shakes .Sounded like a WRX when being reved.After searching about

this problem.It seemed it was running on 3cylinders .I checked coils and ended up being coil #2 (the one with the short in the harness)Swapped coil#2 to

coil#3.The problem still stayed where coil #2 was original at.I then checked injectors and it ended up being Injector #2 when being disconnected did not

effect the idle.I got a used one from a member on here.Swapped it and it turn on,ran perfect & idle perfect.Through out the day,each time when i

wanted to turn it on it took longer to start.All of the sudden it idles ruff/shakes the wrx sound was back .Checked Injector #2 and it went bad again.Can

the short that i had in my coil harness cause the problem in injector #2 or maybe my bad luck on getting a used injector

HELP thanks :D

Ohm out to newer injector. All your injectors should read a fairly consistent resistance.
