HELP! Engine Light / Failed Emissions

Post by mrmike420 »

If you guys can give me a little imput that would be great. My engine light seems to come on only after I reached 60+ MPH, which is usually after 3000 RPM'S in 4th or 5th gear on the highway. My engine is a 92 GS complete stock, so far I added new spark plugs, an air cleaner, and fluids: oil, gear, power steering, etc. Just last week I took it to emissions, I passed all of my equipment and pressure inspections, but failed emission inspection. Results Are:

Hydorcarbons (HC) in grams/mile: My Car: 1.88 Standard: 1.00

Carbon Monoxide (CO) in grams/mile: My Car: 15.38 Standard: 12.00

Oxides of Nitrogen (NOX) in grams/mile: My Car: 4.06 Standard: 2.50

Any insight/ideas would be helpful.....Thx
