Hi,
Just bought a car, an 86 Montero, manual, 2,6 engine. (2 door if that helps :p )
The previous owner had done a smog-check in september, and passed it after: cleaning EGA ports (might say ECQ), dino test, R+R exhaust manifold. When smogging my car today, it failed with huge margains. I will post my previous owners results, as well as mine today.

Previous owner:
Ignition timing: 8 BTDC

at 15 mph
-----------
rpm - 1834
CO2 % meas - 14,90
O2 % meas - 0,16
HC (PPM)
max - 133
ave - 43
meas - 71
CO%
max - 0,89
ave - 0,16
meas - 0,05
NO (PPM)
max 1090
ave 406
meas 624
result - PASS

at 25 mph
-----------
rpm - 1881
CO2 % meas - 14,90
O2 % meas - 0,14
HC (PPM)
max - 104
ave - 32
meas - 58
CO%
max - 1,12
ave - 0,15
meas - 0,03
NO (PPM)
max - 1130
ave - 349
meas - 761
result - PASS

so this was the previous owners results, and made my smog-man believe they manupulated his test, based on my results now 3 months later.

Todays result:
ignition timing: 3 BTDC

at 15 mph
-----------
rpm - 1797
CO2 % meas - 14,5
O2 % meas - 0,6

at 25 mph

CO2 % meas - 14,5
O2 % meas - 0,5
HC (PPM)

These numbers don't say much to me, except that I failed. NO (PPM) has been highlighted with a yellow marker, probably indicating something. Does anyone here work with smogging, and could possibly have a look at these numbers? I would be very greatful, as I can't pay big $$$ right now for a shop to find and fix the problem..
Thanks,
Karl
