This Sunday I had a compression test done on my GSR. It's a 1995 GSR with 92k miles. 1 - 170 2 - 170 3 - 168 4 - 165 I don't even know what to say... ... aren't GSR's brand-new like 220+ psi? I've had the car for two years now, so I don't know much about the car's maintenance history. it had 83k miles on it when i bought it. all i have on it right now is a aem cai and eibach sportlines. what should i do? should i even do anything? it's almost a decade old, almost has 100k miles.
