sorry i forgot this car is 1998 J18 sport
and I do not know ECU rules on idle speeds, at all,
books on J18 super rare, so sorry.
but I do think the pump is bad.
the J18 after all is a more powerful engine, and this ECU has been upgraded like 3 times why who knows. one is key on fuel pump prime is revised.
so fast idle for pump overload will be less. seem logical, that, more power at 800 rpm on 200 more cc displacement/
i have no deep experience on J18, just basics, and evolution of parts.
like this.
long ago did this, helping friend with J18 car.
