Could do with more info, modifications and does it idle ok.
Sticking a PFC in isn\'t going to cure it. Check the map sensor hose hasn\'t popped off.

its in limp home mode. Probably because your stock ecu has thrown an error code. You need to find out which code it has thrown either by putting a mazda diagnostic tool on it or by pulling the code yourself (there is a how to on the net somewhere for the FD).
Then look up the code and solve the problem. Common codes on FDs are those for the oil metering pump and also for the rats nest solenoids

I agree, might just be a sensor on the OMP that has gone meaning that the ECU goes: EEEEK! no oil! and puts the car in limp home mode, check the error codes :)

No mate, the way as has been mentioned is to pull the codes from the diagnostic port.

You need a small diode from maplins and bridge the two ports TEN and GND

It will flash, short flash then quick flashes......so it will read as follows.

3 short flashes will mean 3
5 quick flashes will mean 5

So the code will be 35 :)

There is a list somewhere on the web which what each code is, ill try and find it.

Regards

Matt
