Hey everyone

I have a question about hooking up a 931 wur on my na (with bae turbo)

My car currently does the start then stall thing for about 3x before it decides to start and stay that way. It stumbles at first, but within about 1-3 minutes the idle levels off and stays smooth. After that it will start up[ as though nothing is wrong.

I had bought this off of ebay and have had it soaking in carb cleaner or chevron at one point or another just to help ensure ther might be less gunk in the mesh. when I hooked up the vacuum line I connected it with my boost gauge to the port on the side of the tb (which if I remember correctly is an Audi tb). I hope that is correct - the top port exits to atmosphere.

I noticed in another thread Ideola had mentioned to someone about making sure the fuel filter was connected to the return - which is different from the na - is that something I should worry about in this situation as well?

(new plugs and wires and timing light shows all marks about spot on)


Any thoughts or ideas would be greatly appreciated

Sean

pulled the #1 plug also and noticed it was a little wet - running a little rich maybe?

ok - I started to check system pressure and control pressure - system pressure was at 4.5 bar and steady (with a turbo wur connected)

cold control pressure was also 4.5 bar then dropped to a steady 2 bar after the pump jumper was removed - that does not sound correct - isn't the pressure supposed to drop?

does the vac line need to have pressure as well?

any thoughts?

thanks again
Sean
