Hi all,
Just fitted my genuine used Subaru towbar on my MY04 2.5i wagon.
After re-attaching battery and driving it, it just won't go uphill at speed and is totally gutless in first gear at high revs.
Reset the ECU as per normal procedure and no difference. The mufflers had some rattling when I took them off, and so after finding this problem, took them back off to see if any exhaust flow restriction causing this. Apart from a nice sound there was no increase in power......
The only other thing I did was attach the factory towbar harness into the connector which is designed for it. All connections work on the trailer, so the harness is fine.
Have spent hours on the web, but no ideas - apart from low fluid in the auto tranny (is full and still red as was changed 1 year (7000km) ago).
Only other possibility is slipping band in auto box, but was no sign of this before fitting towbar.
And no, it's not because a trailer is attached!
