4kq Smog Problems, ideas??

[Dave Glubrecht]

I am certain that you have a dead cyl.
First you need to find out which cyl is missing, pull plug wiress one at a
time with the engine running untill one does not make a difference.  You
should also be able to verify spark at this time.  A set of plastic plyers
helps keep you from being the spark tester.
If you haven't yet now check the compression.
If you have not found the problem yet, change injectors with a functioning
cyl (Assuming you still have CIS on this car).
You should now know what the problem is.

Ok, my beater 4kq is having a hard time smogging, the HC topping out at
1900...Gross Polluter is 240ppm...

Is  this likely a leaky exh. valve??  The car has brand new plugs, wires,
dist cap/rotor, O2 sensor, and CO is dialed in.  Only raw fuel could cause
these kinds of numbers, anyone have any BTDT??  It has a bad stumble at
idle, but disappears at higher RPM, noting I can do will eliminate it.

Anyone want to buy a parts car for $500??  ;)

TIA,
