Newbie Question: '92 Hill Stall
Posted: Fri Jun 24, 2005 10:50 am
Being a 'civilian' Legacy owner, I wonder if you fine Subaru heads might share your collective wisdom on the following fact pattern.
I am as always, much obliged.
I've got a high mileage 92 Legacy (auto, no ABS / AB) that reliably stalls when I hill climb. The car loses power and then ignominously stalls. Not all hills, just hills that are either long with an increasing grade or in one case, a hill that is pretty steep. Gas mileasge is also brutal as of late.
After the stall, I can park the car, wait 2 minutes and restart it. The engines runs really rough and out of balance but then calms down and starts driving again, as if nothing happened. It's like it's narcoleptic or somehting.
I also notice that the engine tends to be more cranky in west coast rainy conditions.
My mech suggests that perhaps I need a "de-carboninzing' engine vac which will increase my manifold vaccum pressure, apparently. Having no real car sense, does that seem to be a reasonable course of action?
I've had the new plugs, wiring, timing belt, fuel / air / oxygen sensor replaced to no avail.
When the car stalls, is there a method to decode what the error codes are? Can attach an error code logger than could then be examined after the fact?
