Re: Replaced Injectors.. Still no action in Cyls 3 and 4?
pairs of vertical pins. The other connector has 5 pairs of pins. You will figure out which ones are assosiated with injectors. Though it is tough to say right away which pair realtes to particular injector, you will get general condition of injectors. Normally the ballpark is about 17 ohms. Some of my injectors showed as low as 7.8 ohms . So I replaced all of them with Bosh 19 lbs. My idle is still rough. So that was not the problem, at least was not the only problem....
