Purge Valve on Amazon

You didn't use that throttle body cleaner to clean the MAF sensor, did you?

Alrighty folks... So here's the process that I went through thus far.
I've made videos that I just need to upload to youtube, and will post them shortly here.

First removed the air cleaner and while off recleaned the mass air flow sensor. (Might as well, in here already).

Removed the Evap Purge Solenoid, when I attempted to blow through it... It was CLOGGED. Replaced with this one from Amazon.

Inspected the flex pipe, I seen no signs of leakage anywhere that I could see.
Restarted car and still had a CEL on. (DID NOT CLEAR CODE)

Replaced the 1st Oxygen Sensor with this one from Amazon. Squirted a little penetrating oil, used an offset O2 sensor crows foot.


Came right off. Coated with new copper anti seize and replaced. Bolted everything back together. Cleared code.

Code has STAYED OFF since. My wife has driven the car for the past few days with no issues or check engine lights. I'm going to give it until this weekend to check the permanent stored codes.

I will also post the videos on replacement of the Purge Valve Solenoid and the Oxygen Sensor for all of those interested.

Thanks for the help thus far guys! Really appreciate it!

EVAP purge is supposed to be Normally Closed.

If the sensor came out easy that may have been the leak. Or it may have been getting "lazy".

I was just researching that, Don, if it’s open and you can blow through it and you need to replace it.
So, did you try blowing through the new one?

cturboaddict

The new one- I could blow through.
The one that was on the car- I could NOT blow through.

Maybe I blew through it backwards on the new one???????

If your scanner can monitor live data, I would monitor the O2 voltages, A/F ratio, and long/short term fuel trims to be sure it is running right. If you see negatives in the fuel trim, that indicates a rich condition the car is compensating for, and positive numbers mean lean. You always want to be more rich than lean. Threshold for code setting is -25 or thereabouts for fuel trim rich condition. Numbers are a representative of the percentage of fuel being added or taken away to achieve that yummy 14.7/1 air fuel ratio.
