Here you go:



There are a couple other guys who are running them right there as well. Oh and these are the 1GPH nozzles. So 2GPH total between the two.

OK, so here is an update:

I was thinking maybe the spark plugs had not been tightened down enough when I installed them. So i took the 3 out that were misfiring and re-tightened them down. Put everything back together and guess what! THEY STILL MISFIRE! My injection system is off and not injecting anything. WHAT THE HECK IS GOING ON!!!!????!!!!????!!!!

Do you think I killed 3 of my 6 coil packs ALL at the exact same time? Is that even remotely possible?

Ok, just for kicks I tried putting the stock ECU back in and I still get the misfires. I am at a complete loss right now as to what is going on. I have no idea at all.

You could try moving the coils around and see if the same cylinders are misfiring (do the misfires follow the coils or stay with the cylinders).

Try removing the nozzles and plugging or taping the holes temporarily.

Does the vacuum on your boost gauge fluctuate?

What do you mean by your brakes don't work? Did they completely fail and don't stop the car at all?

 

What's happening with the controller? Do the lights flash/blink on startup?

Do they flash/blink after startup when at idle?

Have you tried disconnecting power from the pump or controller?

 

ok, I am trying to figure out how to test the ICM's because I read a few places that one of those could cause the misfires. I know for a fact it has nothing to do with the w/m kit now since I have completely dissabled it. As for the brakes yes, they do not stop the car hardly at all. They feel like when you pump the brakes when the car is off and you can't push the peddle down at all. I am going to go swap the ICM's around and see if the cylinders change on which ones are misfiring.

It is weird that these things should happen at the same time you install w/m, but stranger things have happened. A bad or failing ICM will cause misfires...I've replaced the ICM twice over the years on my '99 A4 and it has a little over 80k miles. Since you have two ICMs, I'm not sure which one controls which coils. I'll try to look it up in the Bentley. I'm still concerned about your brakes, especially since you have no DTCs or warning lights.

 

ok so i see you drilled into the intake tubes...most S4s run them that way?

 

Are you getting any DTCs besides the misfire codes? I just figured out that you are placing the nozzles right after the intercoolers. That means water is passing through the throttle body. I've said this before, but I've had horrible luck doing it that way. I had to replace the throttle bodies on both my '03 GTI and '01 A4 doing it that way, though not so suddenly.

 

more than 9 out of 10 people run injectors preTB and have nothing negative happen to them.
