Just failed emissions..
Im in maryland... Dont know why i failed... i have the stock main cat and air pump still functional and i have a jdm downpipe. I bypassed the stock fuel pressure solenoid and am running straight off the manifold... Should i have passed?

How many miles on the car (and the cat)? Was the cat hot when you took it to get tested? A cold main cat with a downpipe might not make it. I don't know what the effects would be from bypassing the stock fuel pressure gauge...
One gallon of denatured alcohol to 1/3 tank of gas should get you to pass if you need to in a hurry (it worked for me-- DP, high flow cat and CB), but you should try to find out exactly why it failed if the stock cat was hot. That's all I know.

car has only got like 50k on it... and about 3k on the new motor. my hc was 1320 ppm where the standard is 220 ppm and my co was 6.69 pct while the standard is 1.2 pct...
I ran the car before I brought it in but they made me sit a while so it probably cooled down a bit. Im getting a haltech soon... if i run it lean and (retard or advance) timing... and put in new plugs think that will work??
and what of this denatured alcohol stuff.. Will that hurt my car? and where can i get it?

Before the test, drive the hell out of your car to heat up the cat. Then when you are about a 1/2 mile from the inspection place, put the alcohol in (0.5-1 gal of alcohol to 1/3 tank of gas). Right after the test, fill the rest of the tank with whatever gas you normally use. Then, just to be safe, don't boost too hard untill it all gets out of your tank (by the next fillup or two). You can get it at any hardware store, it's in the solvents section.

Good luck and I hope that this advice can help some.
