Emissions Testing
This being my first post and all....I'd like to start out by saying emissions testing blows. I took both of our cars to get inspected today, a 2001 Explorer Sport and a 98 Dodge Neon. The Neon is my wife's car and has 90000 miles on it. I haven't changed the air filter in five years and the oil is about 10000 overdue. The friggin thing passed emissions. My truck has 76000 miles on it and is well taken car of. It failed the emissions, they said that it was running too lean. Does anyone know what this could be from? I'm thinking either the catalytic or the 02 sensor. Anyone else have any ideas??? I have 30 days to fix it.

If the check engine light came on/is still on, the computer should have a trouble code for the problem. Find that trouble code and you're on your way to finding the problem. Any chance they gave you the trouble code when they did the test?

Get the codes from autozone. Write them down and look them up your self.
The store manager pulled my telling me my TPS sensor was bad and i had to buy a new one. I didnt buy one. Instead i went home and started looking around and couldnt find anything else. Went to a difrent auto zone and some peon pulled my codes, gave me the codes and looked them up. Told me MAF and TPS sensor voltage was to low. Traced the wires from both of them and found that they went into the same rely next to the battery, well the positive terminal was coarding and all i needed to replace was the terminal conactor and a few wires.
