Car dies after 5000 rpms

[92turbors]

I'm about to get rid of the damn car. Stock 92 RS Turbo, after about 5000 rpms what seems to be fuel cut hits. If I keep holding the gas after a second of nothing the car goes again for another second and then dies again. I've checked for leaks and fixed them, changed plugs, wires, fuel filter, knock sensor, even ran 117 octain fuel and nothing fixes it. If I give it partial throttle I can make it to 7000 but any time I'm over 5000 and I floor it the car cuts out. Here is some data of a fuel cut in second gear

Check your ECU caps.

One of them is leaking. I've been putting off buying a new ECU in hopes it's something less costly but maybe it's time to fork out the cash. It would be worth the money to get this nightmare over with. Thanks for the advise.

I just went through the same thing, trust me and just save yourself time and money and replace the ECU. I've replaced so much on my car just to find out that I was right from the start and it was the ECU. At least half my car is new now I guess. If you can, borrow somebody's ECU before you spend a ton of money on another one just to be positive that's what is wrong with your car.

I just ordered the caps. I'll try replacing those first $20 VS $1100 then if that doesn't work I'll get a new ECU. I don't know anyone with a DSM or I would try swapping them out. Thanks for the reply. Hopefully I can get this car running right.

Yeah, might as well try the caps first. Didn't work for me, but might for you. Just make sure you clean all that crap off the board really well. If that doesn't work you can get a new ECU at http://www.foreignecurepair.com/ or Advance Auto for around 300-400.

Put in new ECU and all fuel cut is gone. Runs great now. I should have just done the ECU in the first place. Oh well. I can finally take my car up to 7K.

Car is a ton nicer to drive now I bet, good to hear it fixed your car.
