914-6 Won't Pass Emission Test, (never does...*&$#@^$% bullshit) Options

[Eric_Shea]

I sent Rich some numbers via e-mail but I thought we should post here in case we have some answers that may help others. I just failed both HC and CO. Stock 2.0 six.

ASM Emmission Test

Meas - 573

HC 25mph:
Max - 469
Avg. - 89

I doubt these guys even attempted a hand at the enrichment screws. I used to take it there all the time when the owner would actually wrench on cars (old P-car mechanic... not that old). Now it's just a bunch of melon heads with computers.

The guy took about 10 minutes to bring my car out and then said "sorry it took me so long... I didn't know how to start it" (IMG:style_emoticons/default/blink.gif)

So... lean it out and...?? (IMG:style_emoticons/default/confused24.gif)

I'm no good at this shit... thanks in advance.

i'm not suggesting staying off premium forever, don't get me wrong - we're just talking about getting it through emissions testing.

short version: ethanol burns very cleanly, and it has fewer hydrocarbons per unit volume, so in addition to the clean-burning properties, it also tends to lean things out by giving you less fuel per gallon of fuel. also not a long-term solution :-)

hardware/paint-store denatured alcohol is about 90% ethanol with 10% methanol added to "denature" the ethanol and make it un-drinkable (quite toxic, in fact...)
