went to a shop to replace the exhuast manifold studs, came back from the shop while I was overseas, its been a while since I left, after some time has since passed I don't think I can take it back to those rip off merchants and have them fix what they screwed up without it costing me more money. So if that changed things, let me know what to check first. I don't know what the encoders look like or where they are, so some further information would be awsome. I'll do some searching aswell, hopefully I can get out of this without it costing me a fortune. Finding out they boroke something else would really suck.
