2G Car "locked" above 4000 rpm

[GustavoGHP]

Good night. I apologize for not being word-perfect in English. Translated english

I have a 2g dsm 95, the car works well up to 4000 rpm, it develops normally, the turbine fills, everything normal.
The problem is when it will exceed 4000 rpm, the feeling is that it gets very choked, I hear shots in the exhaust and the car does not develop anymore, I decide to stop accelerating with fear. Sometimes it exceeds 4000 rpm and starts to act like a normal car.

It has already been verified:
*Spark plug cables - NGK BPR6ES (it's new).
*Spark Plug - Silicone 10mm (is new).
*Walbro 255 (is new) + New rewire.
* Leak test impulse - Leaks found and corrected. I found a leak in the intake manifold. But everything is already fixed.
* Cylinder compression test - Ok, 160 on the four cylinders.
* Test with another maf sensor and nothing has changed.

Just changed walbro 255 and conical air filter, the rest is all original.
I have a performance joint installed - Cometic Gasket.

I am currently checking my ecu but I have no experience to tell if it has a problem. I can only see a dark blur near 2 capacitors. Photos attached

I don't know what else I can check to find out what caused this failure.

Again, sorry for my English.

Thanks in advance for your time

Repair your ECU capacitors

yea those capacitors are toasted think about sending in the ecu to ecmlink.com and have them change the board out with a ecmlink one and have a tunable car
