second turbo not running smoothly

[piggy]

when my second turbo kicks in, it has a hold back, not running smooth at all. i have done so much trying to sort it out, but it still doesn\'t help, advise please.....

I would first of all check all the vac lines, the rats nest, located under the plenum is usually the source of most secondary turbo problems and was how I fixed mine. Check for splits in any of the pipes, check incase any have popped off and I would advise to spend the day replacing them all with new vac hose.

I would also advise to check and/or replace all the solenoids in the rack buried under the rats nest.

Do a search on here for tonnes of info..

Hi I would agree with graig,
  I have had the same problem with the second turbo, I found that my charge relief valve had failed, picked up a second hand one and sorted that problem, and on my mates motor it transpired to be a hairline crack in the smaller black box under the strut brace.
  All the best

Dont worry piggy you wont be the only one out tomorrow looking for this problem-i had this happen to me on wednesday night, just as i was showing a rather good looking girl what the car would do!!anyway she is not impressed, think i\'ll name my car christine,let us know what you find.
Anyone point us in the direction of how to test the solinoids etc,and yes i\'ll be hitting the search button in a bit:Thumbs-up
