Shaking while Idling

M

Mishwookie

I have a 1995 Subaru Legacy Sedan and, granted, it is old, but has never
run poorly EVER. Recently, it shakes/vibrates a lot, especially when
idling and it doesn't idle at a constant speed. Sometimes it sounds like
it's going to shut off. It isn't noticeable when I'm driving or when I
have the car running in park, but when I'm stopped in traffic it gets
worse every time. My check engine light has also started coming on every
other day or so, but I'm not sure if that's related or if it's a faulty
sensor, which is what the last mechanic told me. I don't have a whole lot
of money available to me at the moment and have a four-hour trip to
Maryland planned for the end of October, so I guess I'm looking for some
answers that don't cost an arm and a leg. Thanks :)
 
If your a DIYer I would first clean the throttle body. I would also
look for a vacuum leak from a hose pulled off or a bad hose. You say
the cel came on so I would find an AutoZone to see if a code is stored
(they do it for free). If nothing is found get back to us with more
information and or go to www.nasoc.com as their are a group of
experienced guys there. ed

How many miles on the present set of spark plugs? Has it behaved this
way for more than one tank of gas? maybe bad gas.
