Hey all

I am having two problems with my 90 and I am not sure if the problems are
related to each other.   The car has around 70k and with the original
clutch.

Problem #1.  After driving and when I get to a stop light the idle will drop
down 300 and then back to normal.  This occurs with the car in gear or not.
I adjusted my idle to around 900 and the problem still occurs.  I also
recently changed my plugs and wires with NGK.

Problem #2.  When I am accelerating from a start the car will start to
shake.  This only occurs when getting out of 1st gear.  Once I give it more
gas or keep the clutch depressed all seems fine.  In addition. If I am going
up a hill from a start, the car shakes very badly.  It feels like the tranny
is shaking.

Does this mean I need a new clutch? Can problem #2 cause problem #1.


Thanks everyone
