No Boost/very slow revving

Landon353 · Post by **Landon353** » Sat Dec 11, 2010 3:40 pm

Hey guys, alright so I started my integra this afternoon and started driving. I first noticed that my AFR'S were running a little high, and then I noticed that she was lagging ALOOOTTT of power; as in even less than stock. It stays in vaccum and nevers gets lower than 10 (lower as in closer to 0). I checked my throttle body cable and everything seems fine. Also I put it to the floor to see if it would get boost, and my rpms gained slowly even in first. So the second "test" I ran was putting it in neutral and put the peddle to the ground, didnt even go to redline, build boost, or do two step off 6K (obviously with not boost). And now im stumped!! I have had many suggestions such as boost leak, crushed ringland, collapsed cat, and blown headgasket. Im going to get a compression test on Tuesday. So if anyone has any ideas to check, etc. I drove it to campus this morning at 10 am, and this happened when i started the car to leave campus at 12..
HELP please!
Thanks
Ryan

No havent had the chance, tried to get ahold of him yesterday but his number was busy, and his shop is closed on weekends. So hopefully i can figure this out, and im hoping it isnt something major..:PDT_vis:

check the turbo for shaft play and chipping on the fins it might be blown?

I'd check your tps sensor...it sounds like an electrical prob to me..could be wrong tho

So the car doesn't even drive like it should without the turbo part of things?

I would get it to drive fine out of boost before in boost again.

It should still be pretty responsive out of boost.

Can you get any datalog graphs?

you've got a vacuum leak. should be at ~25Hg at idle. when i had this happen, it was the line off the manifold to my boost gauge the broke.

Thanks for all the responses and help guys!!! I just got on christmas break from college so im going to check out all those things, starting with the vaccuum leak. I was also told that my cat may have collapsed and could be majorly restricting my airflow..my tuner told me that. So ill check that out also. Ill keep you all updated and any other suggestions would be much appreciated!!
