Ok, so on Tuesday I took my dart in for Illinois Emissions and well it failed in the HC (hydrocarbon were 2700ppm, only 900ppm allowed). I do not think it could be running that rich but anything is possible. I tuned it up right before going to the emissions place. I am pulling about 14-15psi vacuum at idle and about 12-14psi in gear. And I have leaned it out to almost stalling when put into gear. I am not burning any oil and the plugs are new. However I did notice one major thing. I just replaced the plug wires about 1 1/2 months ago with Taylor wires and the back to drivers side wires are already cracked. When i replaced the wires I spent the $20 and got boot covers for those two since they were right againt the headers and had previously split. I checked the boots when the engine was warmed up and they were at about 160 degrees so the covers are working. I was wondering if this may be why I failed the test (possible not burning those cylinders all the way). Now, I looked Jegs and they have a set of Accell Plug wires that actually have ceramic boots and shielded wires (they are $130 though), would this stop this cracking from happening or do you have cheaper suggestions on wires.
PS> I do have the headers wrapped and the those 2 cylinders are wrapped reall good.
