P1416 is not my friend. Code guru's please help.
Ok here is the long story. I have been trying to get my 96 LT4 through the OBDII emissions here in AZ. I have gotten most of the issues solved. I have sims on the rear O2's and they look OK. I am now receiving the P1416 code. All I can find on it is the Right side Secondary air pump through a code. The issue is, I don't have one. So where do I start?
Is there a place in AZ that could help me out? Is there any one in AZ that does Dyno tuning? I am getting to the point where I am saying bad words trying to get this solved.

Mine was the check valve for the passenger side AIR. It is located at the top rear of the engine (very easy to reach). The vlave is laid out horizontal and apparently gets gunked up.
It was a PITA to get off without bending the tubing. It seems crude but I ended up removing mine with a impact wrench on the valve and a open end on the line. The impact helps break it loose without wrestling so much and bending the line.
The valve itself is cheap (less than 15.00). You can test it by trying to blow through it. Blowing towards the passenger side of the car it should flow very free and not flow at all in the reverse direction. On mine it was nearly impossible to blow either way.
If you are cheap or dont have a parts place handy you can probably clean it out by soakin in carb cleaner.

Yes,what he said ! I should look at what I type,same pump feeds both sides,if pump runs and you only have the one code,change that valve,make sure hose is not kinked(pull hose off pass side check valve,start car,at idle cold,pump should feed air to system for about 30 seconds,you can feel it easily)good airflow,blocked valve or passage=your code.

Thanks for the places to look. I hate to admit it but, I had a kinked hose. I think I have been code free for a few days now. Next stop, AZ emissions.
