Just had the engine on a 2002 Subaru Outback replaced. Accelerator/gas pedal vibrated really bad when I took the car out for a test drive. Mechanic minimized it and said that a lot of Subarus he's driven vibrate like that. I told him that it never did that before. He suggested it might be because the new engine was a 2.0L engine instead of a 2.5L. I told him I highly doubt that. Engine was idling fine and running fine whenever I didn't have my foot on the pedal. Researched online when I got home and sure enough it sounded like the accelerator cable was vibrating. I just checked the cable and the mechanic had forgotten to route the cable through one of the clips. Also, I moved some of the cable pads/insulators around. Just drove it and the vibration is completely gone. So, thanks for the suggested solution on this post.
The mechanic is a decent guy, but it bugs me when they minimize things that I suggest. Kind of like a doctor minimizing things a person knows about their body. I've found that no two mechanics agree on everything and it helps to use the internet to research things. Knowledge is power. Plus mechanics don't know everything. Interesting thing is that several times I've mentioned to mechanics that I researched an issue online and when I say that, they usually pooh pooh the Internet and say something like "you can't trust the stuff you read online." Doctors say that too. Well, I don't trust everything I read online but it does give me ideas of things to consider and check out whether it be my car or my body.
Btw, I'll keep using this mechanic because he's a decent guy and did a great job overall.
