[s-cars] Fuel injector code

Hi!

So the 92 S4 has developed a starting issue over the weekend:

I would turn the key and crank the motor over several times like usual  
but it would not always start and idle steadily.  Sometimes the engine  
idles very low and stumbles, eventually stalling.  When it does this,  
if i shut off the key and attempt to restart the engine, it would  
start and idle normally.  Very intermittent.

Today after one of these episodes it finally threw a check engine  
light, blink code obtained, 4411 for fuel injector number 1.
I removed and cleaned the connector at Inj#1 as an initial step.

But before I go crazy with the troubleshooting (following Bentley and  
SJM site) I wondered if another failing sensor might be reporting  
erroneous info to the ECU, causing the injector to not fire at the  
proper time?  ie, Cam position sensor?

any thoughts?  TIA,
