I hope to God someone understands what I'm about to explain...

Today I noticed that when I shift up off the line everytime I switch gears at a high RPM I hear a *WHOOSHING* noise similar to a blow off valve, but not as loud. Not soon after I started having some engine problems. First thing I noticed was that since I always have my computer reading the bar boost meter I know it normally will go to 1.2 or 1.3 before I shift again. For some odd reason though it will never go past 1.0 now and you can feel the difference. In second, third and fourth gear I will experience a hesitating of the engine at around four thousand RPMs. It'll get to four thousand and just start jerking even with the gas all the way to the floor, but then when I switch to the next gear up it goes great till four thousand again. I don't know if my turbo is shot, if my computer is shot or I have a problem with my airbox. One way or another I'm not getting an appropriate amount of boost. If any information could be supplied that would be most helpful. Thank you.

Sounds like you probably blew the throttle body to intercooler hose...

Remove the hose and inspect it. They like to split underneath and you can't see the tear until it's removed...

It's a $30-40 part at discount parts places like www.thepartsconnection.com, etc...

Until you get a new hose, use lots of duct tape rapped around the hose tightley. That will buy you some time...

If that's not it inspect all other various vacum, turbo hoses and the intercooler itself.

Good luck.

Thanks as always. I'm gonna check it tomorrow. If that's not it you know what I'm gonna do? ROAD TRIP TO YOUR HOUSE! haha

I just wanted to thank everyone for the advice on the hoses. I finally got around to yanking the damn Michelin man hose off and sure enough... HUGE split under the first ridge. I couldn't believe it. Let me tell you guys... if I had taken that in to the shop not only would I have gotten charged for the diagnostic fee, but labor and I would probably have been charged up the keister for the part. I duct taped the hell out of it and threw an extra hose clamp on it and it's almost like it was before it split. I'm going to get the first thing tomorrow. So again thanks everyone for advice on the hoses. I'm slowly, but surely learning my car. I want to know that thing inside and out by the time I get rid of it. Another question though... I think in the process of driving it like that for so long I killed a sensor so that right when I turn the car on my Temperature alarm kicks on. We're talking you could turn the car on and the engine could be ice cold and this alarm will start beeping. Any thoughts on which sensor or how I can just turn the damn thing off for right now? Any help would be great. Thanks again.
