New Clutch... Need Help.

[SandalsBoy]

Hoping someone can help...

I own an 89 GTR. Clutch (OS twin plate) recently died, thrust bearing on the way out and friction plates all but wore out. Took it to the local workshop to have the gear box out. Took me a week to source a new clutch (Xtreme single plate). The workshop installed the new clutch... it works fine. however ever since the workshop put the gearbox+clutch back in, the car now blows black smoke and wont idle without stalling...

Had no other work done to the car besides the clutch... and everything was fine before i took it to the workshop...

IDEAS? Are there any vaccuum hoses near the gear box that could have been knocked loose? Im at a loss as to what it could be... and so is the workshop.

Thanks for your help in advance.

EDIT: PS: wasnt sure to post here or the general maint.. sorry for the double up.

Problem solved: The workshop has spent the day checking and they said that the "tuning" somehow changed. They couldnt explain how this happened by them taking out the gearbox.

Im not even sure how they made the "corrections" to the tuning that they claim they made... because i thought it was all controlled by the ecu... but i thought id post my very poor explaination for a fix in case it helps someone else. Perhaps someone better educated on these matters can add to it for the next person.
