Helppp no more boost

[gn_steve]

Hi guys and gals

Yesterday I degreased my engine bay with engine degreaser and water

Since my car doesn't run right it idles fine but if I give it gas it hesitates and when I try to drive the car it will not build boost and engine rev up to 4000-5000 and no boost any ideas????

Make sure your wastegate control rod has not fallen off the lever on the flapper. Also, verify that all your vacuum lines are still hooked up and intact. It also wouldn't hurt to remove the hose coming from the Mass Airflow Sensor at the turbo inlet bell and make sure that your turbo is not locked up or exhibits any other issues.

Sounds like you may have blown a vac line off with the wash. Check around the turbo and waste gate solenoid.

Cool,
I read your post yesterday leading to electrical problems which is very possible if your seals are in bad condition, but I have washed my entire engine compartment many time with no problem. The hesitation from idle is typical vac related, and no boost if it was one of the boost control lines.
