Ok.... Illinois decided that I had to get the teener inspected... so I did..... it passed everything EXCEPT the Hydrocarbons test. (I think.... thats the one that measures "unburnt fuel" right?) The max is like 800-something, and my car blew 3000-something.
Before ANYONE starts, my car runs INCREDIBLE, and I don't want to change, alter, adjust ANYTHING. Need to know if there's any special "tricks" I can use to get this thing through. Granted, the teener wasn't fully warmed up, cause it's so cold outside.... the gauge was only reading about 1/2 as high as normal operating temp.. would that cause it?? So.. here's the scoop.... the engine has about 6 or 7K miles on it. Its a 2.0, lots of minor upgrades to the heads, valves, cam, etc, but nothing too significant. I have the reciepts (just not with me now), and I know thew PO spent over $5k just on the engine it done right. It's NOT fuel injected.. it has been coverted over to dual Solex carbs.... and I know thats why its probably failing. I know I used to have an 80 Elcamino.... took out the 305, and dropped in a 396BB with a nasty cam. I ran the tank almost empty, dropped in 2 bottles of dry gas, and the thing passed emissions better than a honda Civic--LOLThe emissions guy knew I was full of shit, but who cares.. I passed. Will that work? Will running a teener on dry gas for 20 or 30 minutes severely hurt it?? Lastly... I don't want to be emissions exempt, nor do I want to register it as an antique.. I want to get this thing through inspections just like any other car. Any help is GREATLY appreciated (IMG:style_emoticons/default/smile.gif) |

Errr. It does sound like it is running really rich. From what I've read the most power ain't running rich, so I would consider tuning it properly.
I would look at getting a modern FI systekm like megasquirt, or the other EMS that has been talked about here. It's a lot of work, but I would venture a guess that you have more power yet to get, and you ought to be able to pass emissions, although I don't know how nasty your engine is. Just a guess. |
