Fuel pressure reg is a likely cause but pull the vac pipe off and check for fuel leakage or change in engine note.
Check for air leaks, throttle body gummed up (clean with intake cleaner).

Like i said originally, check the hose between the MAF and throttle body for splits and security - also check the hose between the EICV and the inlet manifold for the same.

If it doesnt stall it will hover around 450-500 rpm. I have tried fitting a new coil, crank sensor, and ignition module still has the same problem. I have tried a different fpr rpm increases if i pull the hose. Has a new distributor & arm new fuel pump etc. I have cleaned the eart leads on the manifold resoldered points in radio suppression relay & fuel pump relay ( clicks when priming ) rsr clicks after a few mins of ignition being cut. Now one thing i do notice is the longer of the two injection resistors gets red hot cant even touch it hot. Any ideas as to what the problem could be would be a great help.

Just in case you missed it Tony - previous references to the FPR and what it's doing on his engine, all points to an air leak somewhere on the inlet side i reckon?
I wonder about the inlet manifold gasket, i think the pink visible ones can leak but thater, green, not easily seen don't?
