I actually have a post up with the symptoms, anyways it all started after a head gasket job, I had disconnected all the main plugs, ecu to engine

 

erractic shift points, maxing out fuel rims, rough idle, 

 

however about 2000 miles ago I reconnected the fuel pressure regulator, in the process I bumped the harness plugs and it ran great for about 2000 miles...  now its doing it again, the fact that is started working when I happened to jostle the harness tells me something happened there

I thought 96 and 97 were also OBD2?

subaru started obd2 in 85, but that has nothing to do with it.

 

when they change the pin out on the ECU , regardless of the reason, they also change the wire harness to match.

the 95 pinout is different than the 96.

96 = 97

97 id different than 98.

and 98 MIGHT be the same as 99.

 

but if you have a bad harness or connector you need to stick with your year.

any idea how big, long the harness is?

where does it start and finish.

not many people harvest the wiring harness.

too much work, not much demand.

 

i assume you have unplugged and re-connected, wiggled, cleaned, pushed, pulled and tapped on the connector in question?

 

i bumped something when i was replacing an axle on my 00 lego.

turns out it was a ground wire i failed to tighten the year before when i did the head gaskets.

the car ran fine until i bumped.
