Help! After replacing cam belt, cleaning Plenum
24. Aug 2011 at 17:40

After replacing cam belt, water pump, cleaning Plenum, Throttle body & breather setup,when I ran it, tickover revs @ 850 RPM instead of 650 RPM.
What Have I done wrong?
I notice when I cleaned the thottle body out,
(I removed both flaps, one at a time, to clean all edges) when I reassembled it, they was not fully closed.
Is this correct?

No. They should both be fully closed.

If you get into serious trouble trying to get them right, I have a pair of throttle bodies for a 2.6/3.2 here.

Is the fully closed position motor driven?

Aug 2011 at 11:36 Thanks for the comments guys. I refitted the throttle body this morning and when I started it up had the same problem, still running at around 800 to 850 RPM when warmed up. I ran the throttle test on Op Com. Now tick over back to 650RPM. Thanks again one and all for your help and offers. Brian
