I am almost positive I have a boost leak and I need some help from you guys. I have a 02 2.7 manual, chipped with GIAC about 5,000 miles ago, everything else is stock. When punching it i get fuel cut off arounf 4500 rpms, and the car shakes alot and waulnt let me go any higher. My check engine light just turned on as well... Is this a boost leak, and if so where should I look to fix it? I have a vag com scanner and im going to scan it later and post the codes. Any help would be much appreciated, thanx.

 

boost gauge?

boost gauge!

 

No, i was just down at H20 and I wanted to pick one up there but didnt have the time on Sunday. I vag-ed it tonight and it said random cylnder missfire. I will post the code tom am, but when i step on the gas it sounds like I now have a bov, when i have the stock divertvalves. What can I do to test boost leak without a guage. (Also where can i pick one up cheap?)

 

The code that came up is 16684- random/ multiple cylinder misfire detected. P0304- 35-00

Any suggestions?

This just popped up. I changed my spark plugs, and now this came up. Could this be the problem with my loss of power?

 

Can't help you find it, but when I chipped mine 4 years ago my shop recommended heavy duty diverter valves and throttle body boot. Installed Baileys and a Samco, and never had a problem. If yours are stock and you have a higher mileage car, either could be the problem. Good luck. PS - I have over 100k miles on the set.
