I changed out that annoying coolant that goes from the block to the TB.Now that I changed that i assembled the car back together.So I crank the car,it backfires,isles like if it had camshaft(jumpy) then shuts off.I've checked all the vacuum hoses,and all of them look connected.I doubled and quadrople checked and found nothing.

I'm thinking it's a vacuum leak,but I'm lost....any help is greatly appraciated

Car is 91 NA Vert.

Thanks

This data is coming from an S4, so I don't know if it's valid, but did you remove the thermowax assembly from the TB? If you did, there is a single vacuum line that goes from the back of the manifold to the TB. Make sure this is plugged up.

Again, I am not sure if this applies to an S5, but there is one line from the manifold to the TB on an S4.

S5 TB's have this as well on the T2 TB, not sure about the N/A.

I just removed the UIM and the mid section if the LIM,there were no loose hoses.I'm going to reinstall everything and check vacumm hoses again.

I did not remove the thermowax,all emissions are still there.hopefully everything checks out,but every input is greatly appriciated.

Thanks
