Failed AZ emissions
I have a stock 91 GT that failed the AZ emissions test today, the
results are as follows: HC = 2.53 / 1.00 standard , CO = 14.76 / 12.00 standard, and it passed the NOX test. Any tips on getting it to pass? My first reaction is to replace the cats, but as far as anything else I have no idea. Thanks for any help in advance. |

Assuming that it's in good condition, start with the basics first. Give it a good tune-up and try again. Joe Calypso Green '93 5.0 LX AOD hatch with a few goodies Black '03 Dakota 5.9 R/T CC |

Take it for a run, you need a good warm engine before the test.

Thanks for any help in advance. > High hydrocarbons... hmmm sounds like a short run grocery getter use lately, not in real good tune. How much oil does it burn? Tune up, Run engine warm blast it out with a good romp & run... change oil, PCV valve and MAKE SURE screen under it is clean. then romp it out for about 10 miles before going in to test. -- Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price you pay..DEAL with it! |
