Did you add a big bottle of techron to the fuel? That helps me pass the NYS smog inspection.

Off the top of my head, how are the coils and wires, PCV's? I hate to start guessing.

One thing is the CATs must be hot, if they do these tests with cold cats we don't fare so well.

Hi Tom,

I have a scanner (3120) but have frankly only used it in static mode. I am not sure if it does real time. I'l go check. Any recommendations on scanners if not.

I did not add any techron or other additive. It may be worth a try. I might swap out the O2 sensors just because they are inexpensive and 20 years old.

I have spark gap a bit high at 042. I might drop that to stock, but I doubt that matters.

In any case, thanks for the input, much appreciated!

Mike
