I am new to the Subaru thing but looking to learn quick. I've got a 2005 OBXT with 67,000 miles. Just picked up the car at 64K and originally ran great. So recently I've been getting a CEL with the code reading that I have a Misfire on Cylinder 2. I'v gotten the code 4 times now. With that said, I re-gaped the plugs (nobody in town has replacements in stock but I plan to replace them next week) after the 2nd time and rotated the coils after the 3rd trip and it's still same cylinder. Due to everyone's comments on here, it sounds like rotating the injectors may be the next step. Now that it's been getting cold out, It's been running a bit rougher after start-up. It's high-speed idol is decent but not perfectly smooth, but once it drops back to low-speed idol, that's when it gets trough (sometimes will shake the body if rough enough). Can anyone give advice? Also, can anyone tell me step-by-step how to remove the injectors (Pictures help but not critical)? Thanks.
