Question: Check Engine Light, Will not pass inspection

Hello: I have a 2006 Caddy Escalade ESV. 6.0 liter AWD. My check engine light came on. A friend has a diagnostic computer tells me it's the gas cap. Replace the gas cap, reset the code. Back to the gas station, still will not pass inspection (Massachusetts). Put the computer on again, it reads canister purge valve. Replace that, reset the codes, still will NOT pass inspection. Kind of at wits end. Need the vehicle for work and cant' use it without a sticker. Also, and I think VERY important. When we reset the codes, the check engine light stays off, but still won't pass. When I refill the gas tank, it always starts hard. I actually have to pump the accelerator to help it along. Once it starts, it starts and runs great all the time. But the check engine light comes right back on. I'm thinking emission?? Vacum?? I have no idea, but will accept all suggestions..

Tell me what code you have in the computer. If your light does not go off then you still have a code in the computer. So get the code and let me know what it is. Then i could help you.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
