Ca18det acceleration missing

I know this is probably simple but I haven't had this problems with any cars before.

My ca18det is miss firing under acceleration. If I get off the gas a tiny bit and ease it on its fine but if I keep hard in it it'll sit at like 4-5k rpm and not increase.

The boost doesn't change, stays at full boost, just isn't acceleration.

What would the most likely thing be? I would guess coils or something similar but not going out buying things for the hell of it cause I'm poor as.lol

Cheers

Yay, just realised its 13 not 31! faark im an idiot, misread it. its collant temperature sensor, Should be simple then. it all makes sense now, temp gauge is not working. this obviously has something to do with ecu and how it runs (hopefully). these things are so much more complicated than a good old carby, dam computers!

Will update if i fix it

Without a temp sensor it's likely the ECU is not leaving warmup mode (enriches the mixture during a cold start). Once it's warmed up however the mixture is too rich so it's not firing. Either that or some ECUs have a time out that if it doesn't warm up after a certain amount of time it either goes into normal operation or "limp home" mode.
