I know this subject gets raised a lot so :sorry: for raising it again.

I have just got hold of a 52mm throttle body. I don't see any problems in actually putting it on the car.

So the question is.

Is there generally any problem with uneven idling of the car afterwards or is that just a Rover 84ps conversion thing? Does the ECU sort itself out?

(Mine is a 1.4 ZR with K&N and a Blueflame zorst already fitted).

Thanks :up:

Mine had a high idle but, i belive it was due to the throttle cable being to tense (causing it to stay open a bit) so i slackened it off and it was fine, you can allways take it to an mg garage for a tune up as mg-rover.org say :D

np,here u go-

locate the throttle body on the inlet manifold,and fit and lightly tighten the fout bolts.working in sequence,use a torque wrench to tighten the bolts as follows-



tighten to 4nm.
back off one flat.
tighten to 9nm

some reason it wont show the pic so if u cant view it through the link heres the sequence-

tighten anti clockwise startin from the top left bolt(next 2 the bracket that hold the cable adjuster,gold coloured and throttle lever)
