As the title states, I have just noticed this problem.... I have no clue what could be the cause or fix soo im relying on ur guys input

I used to be pulling about 20lbs of vaccum and about 22 when off gas during a coast...
But today i took the car out and it jsut sits around 18lbs @ Idle and 19/20 during coast

Also i noticed the turbo always spooled @ about 4k
Now it spooled very slowly nad wasnt fully spooled till about 4.5/5k

It also seemed to be a bit slower than usuall, untill about 5 grand it picked up
IDK but id really appreciate it if someone could give me some pointers!

bump please help

 

I have searched for a long *** time and all i have found which could pertain to the less vac, When the ecu senses a very RICH mixture it opens up the IACV to clean up emmisions and this could cause a controlled vac leak...
IDK, im still lost I am running sickly rich, but why didnt this happen before?

 

anyone?

 

shitty compression maby?

 

you have a vaccum leak, how is your idle? is the car idleing higher than normal??

 

check for vac leaks and check your compression.

 

hey guys thanks for the replys but I have fine compression, and the idle is fine.... IAC counts seem to be a little higher than normal but nothing that would be to this extent.... I bought 2 1/8" compression fittings from ACE hardware, one of my buddys said it could just be a boost gauge leak which im gong to check... ill get back to you guys hopefully its not the rings
