I have a '91 Eclipse GS Turbo. Bought it with a little over 108,000 miles. Immediately went to San Fran for a little R&R without incident. About a year after owning it the fuel consumption seemed to increase. I took it to a local mechanic and Mitsu dealer to have it diagnosed neither found anything wrong. I later noticed that the fuel gauge might be the problem. It's not something you can rely on, as it's always jumpy. It sometimes moves from quarter to quarter then back up slowly again.
One day, while driving from one of my work sites, the rear end of the car started to shake in an unusual manner. I thought a wheel had come loose or something. I pulled over to investigate and found that the passenger side trailing arm had broke (don't ask me how, I still don't know). The good thing was it happened about 2 blocks from my house so I was able to drive it home. I went to a salvage yard on the weekend picked up the whole axle and swapped it out and was up and running again.
My driver side door handle broke. Had to reach across from the passenger side to open the door.
It's burns oil if I idle it for more than two or three minutes. I been told it might be the valve stem seals.
Here's the one that is really bugging me (haven't looked into it yet). Sometimes I loose a little power (it seems to hesitate) between 2000 and 3000 RPM. But then the turbo kicks in and everything is cool.
The body and interior is in damn good shape. A paint job would make it look like a new car. It's got chips from rocks on the hood. Then some a-hole keyed my passenger door (about 6 inch long scratch).
Well take this how you will. My car almost has 130,000 miles on it now. It still runs and gets me around. Still want that STi though. Then I'll sell this car.
