2005 Buick Lesabre Not Passing Emissions. Help or Ideas needed.

[harrycalahan]

We had a Delta88 in the fleet I used to maintain. Had 320k miles on the motor and would absolutely haul ass. I dont know how they had that thing geared in the tranny but it would fly.

So in the end I passed the emissions test. I used a OBD II dongle for the car computer. Cleared the codes via blue tooth and phone. Ran a emission diagnostic for 2.5 days and passed within 10 seconds yesterday when the inspector hooked it up.

I did learn how to clean and replace my MAF sensor and PCV which is weird on the 3800 motor. Not like a regular elbow bend PVC. I also changed my air filter and checked the box and vac lines and all was well. At least now I know how to do it myself and i thank all of you for your input.

I will be searching for Vacuum leaks tomorrow and replacing the O2 Sensor. PCV is easy as well. And its like $3. lol.

02 sensors get dirty, sometimes just spraying with a clearer will do the trick and oil change can help a lot.

It's been 3.5+ years, I hope he's fixed it by now.
