Just ran a pre-test on my 86 4runner 22re:
15mph/25mph -
RPM = 1544/2351
%CO2 = 13.3/13.6
%02 = 0.00/0.00
HC (PPM) = 163/151
CO% = 3.67/3.40
NO (PPM) = 29/17
Timing = 10 BTDC
Failed on the functional Fuel Cap.
Prior to this test, I did valves, new 02 sensor, new exhaust manifold, gaskets, etc, new cat, new plugs and wires.
Old test before I did this stuff was:
0 mph/15mph/25mph
RPM = 0/1516/2443
%CO2 = 7.0/11.3/11.0
%02 = 9.6/2.3/0.5
HC (PPM) = 669/218/196
CO% = 2.75/4.26/6.37
NO (PPM) = 103/193/259
Any ideas on what else to change to get this thing to pass smog? Smog guys said it was air/fuel mixture... Can you even change that w/o a computer?
Thanks,
Eton
