Changed Coils. Ran it on the freeway for 15 or so mile. Numbers change was Stunning.
HC CO CO+CO2 02 RPM WAS:
195 1.16 15.16 .65 1740
After changing coils and getting it hot:
HC CO CO+CO2 O2 RPM
89 0.56 15.16 0.56 2600
Over 100 on the HC alone.
I guess what I learned from this is get the Motor and the Cat good and Hot before you hit the testing place. Changing the coils may have helped some, because it did idle a little smother. But if you were some one who only drove it once a week, you would not notices it.
