1994 S4. Was out driving today, made several stops and on the last one when I started the car had no power. Starts and idles ok. Limped home and found that when I diconnect the plug wires from the centeer 2 cylinders, there is no change but they are sparking. I diconnect either of the 2 end cylinders and the car will die if I dont connect it rigth back. I did the same with the injector power connecter and it does teh same thing. Freescan shows no erroe codes. Any ideas? is there a relay or fuse for the center 2 cylinder injectors?

I did clean the engine today but had it warmed up first and made sure there was no standing water etc afterwards and let it idle and warm up for awhile. Again, went for a drive and all was well until about the 4th stop.

Thanks!

Found it is a back injector. 3 show 2.6 ohm and one of the non firing shows 1.3. I have a set ordered from JAE.
