Question about 1991 Subaru Legacy

1 Answer

No power, idling rough

Engine fires up straight away and runs fine, however, after a short drive it loses power rapidly and idles really rough to the point where it seems as though the motor might jump out from the engine bay. Have tried everything I can fuel system, coils, spark plugs. Is it in the turbo or maybe head gaskets? Also rattles while running to the point that its embarassing. Have tried running a multi grade oil but still hasnt fixed the issue. Are the issues maybe related? Car is a 1992 2ltr turbo 4wd legacy. Please help Car drives fine cruising at 80km but when i try to give it a little more gas it wont pick up speed, also if im going up a hill i cant get any more power out of it, when i pull over after the hill it idles really rough like the motors going to fall through the engine bay. After waiting for a couple of minutes it is ok again - untill the next big hill.

Main engine control fuse blows out


One thing missing when running at idle is road vibration. Try a wiggle test on wiring to see if there is a short to ground anywhere. Only thing I really hate when doing this is that I have had problems like this disappear after doing test and not re-appear for a year or two, because the wires got moved enough to keep the bad wire off of where it had grounded.

Rough idling and poor fuel economy on 92ford f-150


This whole problem is most likey due to a sludged up intake and idle speed control valve, do the following procedure and it should take care of the problems, also run a couple of cans of LUCUS brand fuel injector cleaner through, I know u will see it is more expensive than other brands, but the thing is it works!
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

ROugh idle


there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
