hi guys i have a 91 s5 n/a, i replaced my omp lines and oil cooler hoses, and when i turn the car on it just shuts off, i tried to adjust the tps by increasing the idle screw but the idle is really low but stays on now but just beraly, could it be the upper intake manifold gasket, or the thermosensor which i found out i broke when i removed the uim, i have yet to buy the thermosensor

 

No breaks at the vacum spider or oil injector lines? Same area and easy to bump when doing the oil meter lines.

 

If you didn't replace the intake gaskets, you'll create vacuum leaks. You can also create some by improperly reinstalling the manifold.

 

okay so i should check the gasket uim gasket, the gasket is new, but i didnt put sealant, i just put it back on, i doubled checked all the vacuum lines and their all connected, so i guess recheck the gasket area

 

I never use an RTV/sealant on the intake gaskets, but you could loosen/tighten the bolts/nuts. If you tighten the bolts on the driver side before the ones at the intake runners, you can end up with the manifold sitting at a slight angle.
