Emission Failure

[patricksmustang]

I thought I did but apparently not. The plugs were changed about 4 or 5 months ago but just plugs. Wires have been on for about 2 to 3 years and it could use a new dist cap and rotor and I probably have about 2000 miles on the last oil change. Fuel filter, pcv, air, and breather filters are all new. I didn't run it for a real long time before testing maybe about 15 minutes and had hi test gas in it. And my driving has changed for alot of freeway driving (30 to 40 miles one way to work) to 3 or 4 miles one way on the back roads. I sure could use any other help you may have and thanks for the previous info, I will definitely follow up with that, just didn't know if I needed to look for specifics within the emission system itself and yes ga does use the dyno but I passed it last year.
