Intake not Sucking air gtp

**kyleinkman** · 07-28-2011

Hey so my 03 gtp has starting acting up today, My CAI is barely sucking air at all and my gas milage has died aswell. Ive cleaned the MAF and got rid of the carbon in the intake already. even with the K&N un attached it is still sucking little to no air.. Ive checked all the vacuum lines i can see but im open to check again if theres one you guys suggest im failing to see. Does anyone have any idea what could have caused this? was working great yesterday thanks in advance.

clogged cat? is the car gut less as well? like no power.

**kyleinkman** · 07-28-2011

cats not clogged its only about 2 months old, it has power but a sig loss since yesterday

have you tried spraying some carb cleaner around the engine yet, if the idle jumps, you have a vac leak.

**kyleinkman** · 07-28-2011

yeah i did that when i cleaned the maf. is there any significant hoses for the Intake that i should double check? also would this be my supercharger going?

**Scottydoggs** · 07-28-2011

one of the more common ones is under the sc snout, the one with the T fitting.

i dont think your sc is going bad, something else is going on.

Air's got to be getting in somewhere for the engine to run. Look for a big-ass hole. You can't miss it.

Is your supercharger belt off?

**kyleinkman** · 07-28-2011

sc belt is on, the one with the t fitting with the harder hoses?

boost control is not holding the butterfly keeps dropping should the pintel stay up or should it drop down to hold boost or should it drop to release the boost?
also oil is leaking slowly from the base of the snout could the upper intake gasket failing cause this? belt isnt loose or slipping. i have an fuel system lean bank 1 code. no other codes.

Only advice i can give is get some carb spray... Spray around and wait for the idle to trickle up and down find the leak

vaccccc leaks......

oil might be the snout fluid.

cant tell without looking at it.

**JoRoW99** · 07-29-2011

Supercharger oil will only leak from the snout fill plug, the plug thats on the end of the pulley, and the seal between the snout and the case.

**matt5112** · 07-29-2011

it leaks from the snout seal at the pulley, the seals in the rotor pack, rotor pack plate and s.c case as well.

leaks anywhere it wants really.

I should not have used the word "only"

System 1 Bank Lean is a vacuum leak.

Find it.

**Sandman** · 07-30-2011

How's your PCV valve? Could oil from the blower mean a bad seal? That could be the source of the vac leak.

**blueguy** · 07-30-2011

PCV though when toast most of the time squeals really loud...

**kyleinkman** · 07-30-2011

so far today i have changed the fuel filter. problem still persists this vacuum leak is being very difficult to find. I guess my next option is carb cleaner and a camera.. maybe you guys will hear somthing im missing
