MPI fuel injector specs
 

Does anyone have the specs for the injectors? At idle and off idle. I have one that has 5.0-6.0 ms at idle and off idle it is 3.0-3.9. It seems to be backwards? It idles really rough and alot of fuel. The FACTS-New motor,distributor,computer(merc),alot of new sensors, etc. Also with the scan tool in service mode to set timing,The motor will actually rev up and kinda clear out. WEIRD!!!! PLEASE HELP !!!!!

What year and engine? Newer MEFI style engines when in by pass mode will rev uo on it's own normaly anywhere from 1600-2000 rpms.http://www.michaelstractors.com/foru...p?TOPIC_ID=199 I am not sure this site would help you or not but their is some ok info in their all about MEFI stuff.
