Failed Inspection.

CorSVXette · #1 09-14-2009, 09:13 AM

My car just failed the inspection. He said my emissions was too high. Any ideas why and how to fix it? He put a bottle of some cleaner into my gas tank and said to run the tank down and then refill it and bring it back in. The stuff he said is "guaranteed " to pass inspection. We shall see. He did not charge me so no loss here. Just wondering what would cause it to fail? Thanks.

Do you have a print out saying what specifically was too high? HC count, NO2 levels...?

Yeah a printout would be helpful, theres many things that could fail you, and the particulate level indications could narrow that down a lot.

If not, start with the basics, spark plugs, fuel system cleaner (thats the guaranteed to pass), check for vacuum leaks, etc. The worst it could be is a bad catalytic converter...... also did you drive it a while before the smog test to get the engine and cats hot?

I am kicking myself because I left the printout there. I did not drive it very long. Maybe a 10 minute ride to the shop this morning after sitting all night. The plugs and wires were changed not very long ago by YT. Probably less than 1 year ago.

I am going to take a ride back to the shop and get the print out. Stay tuned.

2. HC 250 ppm CO 0.53 Pct. CO2 13.7 Pct. NOx 98 Pct
3. HC 258 ppm CO 0.52 Pct. CO2 13.5 Pct. NOx 108 Pct.
