[QUOTE="Lethalthreat7.3, post: 1174950, member: 10651"] Sounds like a uvch issue. If #1 is buzzing and you changed the idm(no difference) then the other three on that bank should buzz as well. Vref is the same for all four on the left bank with a different but common Vref for the other four on the right bank. Not sure if you tested at the uvch's or the 42-pin but try using a 200ohm scale meter and ohm out each injector to the correct vref for the corresponding bank.(sorry don't have the pins/pic handy) [/QUOTE]
