Today I took my car in for a smog check(CA :?) so that i could finally complete the registration process of my 3.8 N/A Regal. Before i bought the car, it had been sitting for almost two years. Since buying it, I've filled it with new gas and changed the plugs and wires. Unfortunately for me, It still failed. Everything was within range except for the hydrocarbons. It barely skated by with 89 ppm at 15mph which is the max for that speed, but failed at 25mph with 14 ppm over the max allowance. I plan to change the oil and pcv valve this weekend, anything else? I really need to get this thing over with. Thanks in advance.
p.s. Keep it legal, please, the DMV is making me go to a strictly monitored STAR station.
UPDATE: So after changing the plugs, wires, oil/filter, fuel filter, air filter, pcv valve and this time running it for about 40 minutes and leaving it running until the test, IT STILL FAILED. This time the HCs were fine at 15mph, but it only went down to 10ppm over the max allowance at 25 mph. Both a friend of mine and the smog guy suggested leaning out the air/fuel mixture. My budget is tight, so I'm going to try leaning the mixture out myself, but I've never worked on a carb before. Is this something fairly easy to do? It's just the standard 2bbl.
