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 HC 15mph: Max - 509 Avg. - 109 Meas - 573 HC 25mph: Max - 469 Avg. - 89 Meas - 401 CO 15mph: Max - 5.07 Avg. - 0.76 Meas - 10.17 CO 25mph: Max - 4.97 Avg. - 0.77 Meas - 9.57 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. |

It's a PITA Eric. BTDT. 'Specially at altitude. I can't add much to what has already been said here. Except...
The hotter you can get it, the better off you'll be. In addition, find out what the idle limit is and bring the idle up as high as you can. It helps bring the numbers down. High HC is why I bought the MSD for mine. If your ignition system is in good order, then retarding the timing *should* bring it back in line. |
