Hey all! New to the forum. I own a 2003 Subaru Impreza 2.5 RS with 210k miles on it. I bought it used at 207k miles. I do have an extended warranty and have it going into the dealership for repair come a week (backed up due to holidays).
Here's a history of issues. About 2-3 months back it started having idle issues to the point where RPM will dip to 100 and then steadily toggle itself back up to about 1k. It isn't all the time but when it acts up it stutters. Not every drive does it do this. Anywhom I checked spark plugs and spark plug wires, they look to be in working order and do not need replacement (from my limited experience). The check engine light coded out for 02 sensor and a cylinder 1 and 2 misfire.
More recently I was on the highway driving and it would not accelerate up past 70-80 MPH in 5th gear. Check engine light was flashing, indicating a misfire issue. It would continue to accelerate and function in 2nd, 3rd and 4th gear. When I got it to a stop light off the highway it died twice. I was able to drive it home without issue after I let the car sit. It idles well for the most part until the mercurial issue arises.
Upon doing some research it occurred to me it might be the MAF sensor. My understanding is the MAF sensor can be cleaned and it might be the issue. I've searched around and tried to locate it, I have pictures of my most recent attempt to find it and clean it in an effort to keep the car running until my appointment and have a driveable car.
Here are the pictures of what I thought I found to be the MAF sensor. From all that I've seen online this isn't the MAF sensor. Where would I find the MAF sensor on this specific model, and from what I'm experiencing does it seem to be an MAF sensor issue?
Would appreciate any thoughts and input.
Thanks , this is my first post and hope to learn more about my car and maintenance it well. Love this car in the short 3000 miles I've driven it.
