i'll take a look into the plenum see if i can see anything tomorrow. thanks for your help guys. keep em comin if you have any other ideas.

 

so i checked 2 things over the last few days. i checked the plenum and it seems to be fine. i also did a compression test on cylinder 7 and came away with 160 psi. yall know if thats a normal reading or is it too high/low?

 

Nothing wrong with 160. And as far as that tsb test goes for the plenum. I believe it will only show bad if the leak is really bad. So you might want to pull the TB and look with a mirror.
