My idle surges from 1000 to 1500 like every 2seconds. It only does this after boosting. Truthfully, I don't even know what I'm supposed to be idling at. I do not have a CEL activated. I am only using one check valve; then I went to two. Even after the extra check valve my idle problem remains unsolved. I have not tried adjusting the idle by the throttle body because this only happen after I put on my turbo. NE advice would be appreciated, thanks.

Possibly a vacuum leak for your blow off valve?

Check for vacuum leaks.

Other thing is, does it settle when the engine gets to operating temperatures?

And if its a manual with all the accessories off, it should idle around +/- 50 @ 450 and automatic +/- 50 @ 550

450/550 what? take a look at your hood, its normally 750 +/- 50

I looked at the hoses and everything seems ok, but I am going to go to the Zone tomorrow or tonight, we have a 24 hour Auto Zone. I don't know if they are that popular, but it sure helps when you drive second shift.I will replace all of my vacuum hoses and check my czech-valves

A bad tb gasket could cause that also.

HMT-Admin
