Do I need a new ECU??
I have a 95' hatch with a JDM B18C.
I have a problem: it is running too rich. de CO level is good at idle, but it gets too high when testet at higher RPM. The car runns like ****, it fires in the exhaust when i shift at 4-5000rpm, and it strugles to get to the redline. My apexi RSM shows the car has like 70-100hp and not 200-230hp as before
This **** started suddenly, when driving it in the city.There is no CEL code.

I have tried this:
New Fulefilter
new Sparkpluggs
new Dizzy
New Map sensor
Help me I'm so frustrated right now

Thanx for any reply

JDM B18C
JDM P73 OBD2a
