[Shotimes] IAB Question

[Robert A. Pittman, Jr.]

My 90MTX won't maintain an 1100 rpm idle.  Sometimes it'll idle down to
nothing and die.  Sometimes it'll drop only to 1000 rpm.  Anyway, the usual
suspect for such cases is the IAB.  I saw a procedure for cleaning the IAB
on the FAQ, but was wondering if I should just go ahead and replace it.  The
car currently has 125K on it.

Also, is there anything else I should look at that might cause this problem?
If there is, like the IAB, should I clean it or replace it?

Thanks for all y'alls advice.

Regards,
Rob
