4jx1 engine fault
Posted: Tue Jan 12, 2010 4:26 pm
Gday, got a 4jx1 at work that runs sweet at idle, sweet top end but just off idle (around 1000rpm) it runs rough. Have replaced the rail oil pressure sensor and the injector loom as it was leaking oil. Rail pressure is right but the injector pulse width is all over the place at idle but sits smooth at higher rpm. Any ideas apprieciated.
