April 23, 201015 yr Howdy all ! I have a 1993 Legacy that is really sluggish lately. It is very slow to climb hills and accelerate on the oped road. I tried changing the wires and plugs as well as fuel filter, transmission filter and oil. There is no Check Engine light on either. Any thoughts on what could be causing this.
April 23, 201015 yr Author I used NGK both. Would the catalytic converter make it slow? Like I said no CEL on
April 23, 201015 yr Would the catalytic converter make it slow? An exhaust system restriction is one of the things that can cause the symptom you've described. It's possible to use a vacuum gauge to check for that.
April 24, 201015 yr Author It does use some oil, but not alot. Are you thinking it might be the rings?
April 24, 201015 yr It does use some oil, but not alot. Are you thinking it might be the rings? Yes. A vacume gauge will help rule out many other things, and if it is dramatically low, will point to bad compression. nipper
April 24, 201015 yr Author Do you put the guage in the spark plug sockets? And what should it read if the compression/exhaust is good? thanks-
April 24, 201015 yr http://www.classictruckshop.com/clubs/earlyburbs/projects/vac/uum.htm no you connect it to a vacume line.
