Stumped

[Vincent Gelinas]

Ahhh... Oops! I misunderstood the directions.   I'll have to try it 
again once I grab a 13/16 spark plug socket.  A neon spark tester? Never 
heard of it.  Only heard of a test light.

  The gas is only a couple weeks old; I've gone through a few tanks 
since I've had the car.  A compression test would be very interesting 
indeed.  I'll have to see how much Autozone charges for a deposit to 
loan their kit out.

A vacuum leak? I've been thinking that.  Does anyone have a vacuum 
diagram of the 90q/NG?  I've looked online and can't find one (and the 
sticker on the bottom of my hood is missing)

Thanks
