Decat fitted engine light flashing

[Jeggz16]

Hi iv recently had a decat fitted car was running fine, yesterday driving the car almost went into limp mode and running terrible making terrible sounds from the exhaust. The emissions light is now constantly flashing. I have connected my diagnosis machine up and it’s not showing any fault codes. Any ideas? Any help would be appreciated cheers.

The should be a code stored if eml came on or is flashing.
Most time flashing eml points to misfire detection

Usually when you fit a decat and the light comes on it's a constant light not flashing and doesn't affect performance.
Sounds to me like the lights flashing for a different reason.
I've certainly never heard of it putting your car into limp mode.

Flashing EML and rough running will usually be an injector. Take the fuel rail guard off and while it’s running unplug each injector and see which one makes a difference, the dead one should be pretty obvious to find.

Are you sure you didnt damage the precat sensor? Most likely injectors anyway and decat is a coincidence
