For some reason my car has a major feul cut problem at 3000 rpm in all gears.
I check the tps, boost sensor, and timing. could the sensor on the back of the water pump cause this feul cut problem because my is broken in half.

I aslo heard that adding more ground to the motor would probadly help.
If this is true what's the right way to create more ground.

 

silly question but are your sure your fcd is doing its job?

 

Do you get this fuel cut when in neutral and reving around 3000 rpm?

 

the fcd is working fine because it's letting me reach up to 10psi. and it rev good on neutral. i guess the problem is ground issue. what do you guys think?

 

If you have a Racing Beat Exhaust, I believe that you would need to install their Fuel Cut Controller. That part prevents the computer from shutting off the fuel when it detects overboost conditions. The S5 Fuel Cut Controller P/N is 11571 and the S4 P/N is 11570. I have a RB system and the Fuel Cut Controller eliminated the problem that you are experiencing.

 

Does it happen especially bad when making left turns? I had a FC that did that and it almost caused me to get hit by a bus... So I didn't drive the car for about a month.. And it basically went away LoL... I regrounded too.. that might have helped.. I've seen a couple cars cut at 3k with bad grounds..

 

I have a fuel cut defenser on my car (fcd)

 

when you regrounded your car before you crash it. did it help at all. and on rotary resurrection I read on how to reground an 2nd gen does it really work.

 

yes it really works on rotary resurrection.. just go get a spool of 12 gauge speaker wire and some ring terminals at ur local autozone or whatever it is.. and then start grounding.. make sure u clean all the surfaces on the ring terminals and put solder over any wire thats showing to ensure a good connection..or you could also just redo the stock grounds by cleaning them off or replacing the ring terminals and soldering them in..if u wanna save a whopping 20 bucks..couldnt hurt to do both.. just in case

 

I'll Try It Out And I'll Let You Know If It Help Or Not.
