Need advice with 1991 Subaru Legacy stalling
I have a 1991 Subaru Legacy SW. The problem is that it keeps on stalling at the top of hills! Near the top of long hills, the engine begins to stutter and loose power until the car comes to a complete stop. It takes a minute to recover and then we're off again without any problems at all until the next hill climb! I've check the fuel and oil - no worries there. Any ideas?
On the other hand, it could have a head gasket or other major issue. So, run it through the paces on one or more test drives, look for seepage at seals, gaskets, etc., and look for any gunk (black specs, oily sheen, air bubbles) in the coolant overflow, etc. Inspect the CV boots, brake pads, do some figure-8 turns to check for any differential binding, etc. Above all, check the car's fluids! If fluids don't look good, you'll likely be in for some significant repairs down the road as those are the surest signs of general neglect.
Yes, $7,000 is quite a bit for those miles, but the age of the car comes into play as well. Some damage & deterioration is very much a factor of age, so a six-year-old car will likely be in better overall condition than the same car, ten years older, with the same miles.
I have the same 2001 Subaru wagon with the same problem. I have a manual transmission. I have completely eliminated the stalling problem on long uphill grades by downshifting from 5th gear to 4th gear when the rpm's drop below 2500. The higher rpm's in 4th gear take the pressure off the engine. As soon as you feel any tremor, downshift.
