'97 outback 2.5 auto 190K..when in neutral/park it revs fine...when in gear it stumbles...any help appreciated...

Maybe needs tune up with spark plugs, and maybe spark plug wires.

Any check engine light?

Any recent work under the hood?

When was the last tune up?

When was the last timing belt change?

Possible catalytic exhaust partially working- as stated earlier, check eng light on?, codes to be read, mine idled fine, stumbled to bog on load(was bad cat due to HG issues) have Head gaskets been done?

clarify

head gaskets done via steel-seal...no over heating...I don't drive this car...the wife does...codes indicate a knock sensor and miss-fire on 3 outta 4 cyls...I really don't like the look of where the plugs are...any tips on making the plug R&R easier on my old busted down back????

 

 

oh...I suppose NGK plugs and OEM wires???

 

 

thanks guys...))

Change knock sensor first. Chase misfire codes after because knock sensor can cause misfire and low power issues.

 

Plugs aren't too bad if you move some stuff out of the way (washer tank,etc) and use a short extension and swivel or universal adapter on the spark plug socket.

 

NGK or OEM recommended for both.

thanks budz...:cool:
