There are numerous vacuum pipes for this engine, I wonder if you've maybe disturbed one?

Didn't you say that you were going to take off the air intake pipe from the air filter to the engine? There is a small vacuum pipe there that you might have disturbed, and this might be affecting your idle.

I'm going to double check them all..i ended up simply checking the maf sensor..pete put me right before I tried spraying carb cleaner into the inlet and I ended up using my diagnostic instead to check sensors

Oh aye, best to listen to Pete he has a wealth of knowledge and best of all he likes to share it...
