Full throttle switch

[Jad Duncan <Jad.Duncan@gat.com>]

I just rejoined the list and think this message failed the first try.  If
not, sorry to have wasted the duplicate bandwidth...

I have an '89 90q with an intermittant check engine warning light.  The
light 'tends' to come on when going up slight inclines on the freeway and
goes off if you increase or decrease the throttle.  I ran the computer
check and the only error was 2123 which is for the full throttle switch. 

My question is what does this switch do and why would the check engine
light come on intermittantly when not a full throttle if the switch is the
problem?

Thanks
