Wednesday night i drove home from work all fine, Thursday morning I took off my intake, as well as the connecting piece to the throttle body (CAR is a 1991 NA coupe). One wire connecting to the bottom of the intake and three vacuum hoses. I did this so i could tighten exhaust manifold bolts and upper intake manifold bolts. put everything back together and NOW THIS HAPPENS

 

Sounds like a vacuum like going on. I could be wrong though.

 

Are you sure you connect those hose & that connector at the right place? Are you able to take a pic/video of what you did exactly

 

yea i could make a video but I PROMISE anyone else who owns a NA S5, knows, 2 medium and 1 large vacuum hoses connect into the intake with ONE electrical plug in. COULD THIS BE FUEL PRESSURE RELATED? I replaced the LIM and did all the work that went with it, I could not simply turn on my car after that. I needed prime the fuel system, I HAVE TRIED priming the fuel system for this latest problem but no luck. I drove the car for a week with no problems until just thursday afternoon when I took apart my intake to make it easier to tighten bolts.

 

Recheck your work..Have you plugged in your Air Flow meter?
If it ran before you touched it then what you did was not put it back to the original state!..**** happens,you forget something..go back and look.

 

MY CAR WAS WICKED FLOODED!!! if your car sounds like mine did from the video, and the spark plugs are wet, do WHAT I DID!

Go to rx7.com, read through the tech articles and find the one on deflooding! IT'S ACTUALy one hell of a show, smoke show lol. it works though, for real!
