No throttle response and bad idle after cleaning TB and painting manifold

Hey

i have a big big problem.
I removed the manifolds (for painting) and the throttle body (for cleaning)
Also i changed my spark plugs.

Yesterday we put everything togehter but the car is idling very very bad.
There is also no throttle response, check engine light is on.

We checked everything if there is any air leak or somehting like that, but found nothing.

Ideas?

Thanks

Patrick !

unfortunately sometimes when you clean the TB this happens.

Did you swap the bypass valve and TB connectors by accident?

Maybe throttle need to be reset, via STAR/SDS, to let it functional (as it's fully Electronic/data)...!

ZAYED,,

it seems like he only removed the surge tanks not the super charger

if you don't have access to DAS search for manual TB reset procedure

I read that this happens often.

But as your CEL is on, i'd diagnose it with SDS asap.
