2003.5 MSP
My 2003.5 MSP started jerking two days ago. I had a forge blow off valve on it before, but it still jerk after i put the factory back on. My only mod on the engine is a cold air intake, and boost gauge and the joebmc, i have removed all the mods and now only cold air. Unplugged battary it still jerks. it nowhas no power at all. you can hear the turbo working but then the car jerks..i checked all the piping for leaks and have tighten all of them..no thing helps..does anyone know whats going on??please help..!!thanks!!
 
The pipe that goes form the turbo to the intercooler is known to crack, make sure you check that as it will cause a vac leak if it were torn, clamps, vac lines anything that will leak can cause the bucking that you're refering to just go back and check everything again.

I retighten all the piping..it appears to be normal again..thanks!!!
 
my car does the same thing i only have a cone filter and hks bov on mine and it stutters hard. turns out the boost sensor ontop of the cold pipe came off entirely and had a huge hole in my cold pipe, they dont make plastic like they used to
