Re: And what are the symptoms you are feeling while in the car?
Well heres what is going on, in the morning when I first start the car it will misfire a lot until the car goes into closed loop. Once in closed loop the car will run fine after driving the car for 20 to 30 min it begins to have a slight miss between 2500-3500 and will not make boost or accelerate. If I let off the gas the gauge boost shows zero vacuum, if I give it gas the RPM will slow start to come up but only make 2-4 lbs of boost. This will happen a few times then the car will take off like a rocket and run fine after this happens. The odd thing is the CEL only comes on every once in awhile. So far I have checked the vacuum lines but none are broken or loose. I thought it was bad gas but its been happening a lot more lately. Also noticed that ther is a small amount of oil coming out of the dv/bov I think the pcv is failing but I am not sure about that. I change the oil every 2500 mile like clock work and it only gets 91 or 93 octane. I am going to pull the plugs and check them, is there anything else I should look at?

I would guess it's 1 of 3 things, first thing I would try is cleaning out your
throttle body with throttle body cleaner (not carbeurator cleaner), second could be your coilpacks, and there is a small chance it could be your MAF sensor. I say to try the throttle body cleaner first because it's cheapest, but if it's most likely your coilpacks.

Re: Help with codes
Ok here is what I found, first was a broken vacuum line to the Secondary Air Injection Solenoid Valve, so I replaced it. Second I pulled the plugs they looked ok but will need to be replaced soon, I also found carbon tracks in all of the coil packs, so I think I will have to replace those too. I cleaned the MAF (I found a feather traped between the screens, so I pull that out. I cleared the codes in the car and drove it only thing that came up was the Secondary Air Injection Solenoid Valve code, so I think I have to replace that before I do anything else. What do you guys think?
