Hi ART,

I am with you on having four injectors at fault. I can go with one questionable injector or o-ring seal, fixed by four “fresh” ones and fitting correctly!

His other question about timing advance under a hard acceleration is something I have not thought about in a long time.

I think it has to advance more degrees BTC in order to match engine piston speeds and to give more time for the added fuel/air mixture to ignite.

The ECU map and the knock sensor play a part in that.

Probably the reason for the diaphragm to disappear in later years as it did not work as well as the better fuel management systems. They would probably like to get rid of the FPR but there are too many variables for a proper volume of fuel delivery.

Of course, like the o-rings I do not know how “fresh” my memory is on this either.
Phil
