R33 Spec 2 wont rev...

Recommended Posts

https://www.youtube.com/watch?v=mUt3KAQ_RlA

First of all, sorry for my bad english, i'm from finland!

I've got this car for week now, and i have driven 1000km with it before this weird problem came...the car has aftermarket ecu, and Vag-coils. I have tried with other sparkplugs, coils, cas and tps. I don't know what to look next, any ideas. ECU has bad fuelmap, and its going to get adjusted. The car still worked with this map for 5000km...Now it wont work at all, sounds like engine chokes when revving.

Could be;

Failed/failing fuel pump.

Bad AFM. Dirty, poor connection at plug, broken solder joint.

Bad CAS. As above.

Vacuum leak.

Boost rag.

Blocked cat.

The list goes on.

Take it to a mechanic.

Seems like the problem is bad MAP-sensor. Tested hose for sensor and there was no leaks. Car runs same MAP on/off. I'll update when i get new sensor and see if it makes changes!
