Whilst this replacement has cured the zeroed speedo, the loss of power issue is now constant. Here are the symptoms:

- Chugging/stuttering at cruising speed (~60mph) as if I'm driving into strong winds (constant)

- Noticably poor acceleration with definite loss of power as compared to before the new VSS (constant)

- Drag or lurch when changing between low gears (frequent)

- When in neutral the revs stay high for ~5 secs then slowly return to normal (occasional)

Now this would only happen when the needle was stuck on zero prior to the new VSS, now it is constant. I read somewhere that it could be the EGR valve, but I had a look and don't think I have one! I also unhooked the battery to reset the ECU to no avail.

Does anyone have any ideas? I'd really appreciate the help.

Thanks!
