Context: This is an '84 GTI engine in my '81 S1.

1.8 liters, GTI 'big valves', yada, yada.
154,000 miles, internal mods unknown, prob. none.


RPM	1054
HC PPM	  17
CO%	0.00 (?!)
O2%	12.4
CO2%	6.2

TBerk
w/ wrong Dist, Leaky Exhaust joints, and old tired sparky plugs.
ND said my CO2 was way high, prob. due to leaks in the exhaust.
