alright thanks guys. i have a HAI. i do have that small leak in the crossover on the headers but hopefully will be able to fix that tonight. i have a p0135 code come up twice so im gonna try changing the o2 sensor also. and then when comparing my vac to a couple of my buddies at work today im only pulling about half the vac they are. dont know if it matters that ones a turbo cobalt and the other is a supercharged civic si but i would think i should still be getting about the same vac as they do at an idle. they are getting 20 and im getting bout 9.5 or 10 so im pretty sure ive got a vac leak somewhere just need to find it. also on the to do list is the fuel filter that never got changed when the new engine got put in so i dont know if that f'ing anything up to.
