Okay here it goes. I have a 1995 K75 that will not run right. It starts and runs, but it runs rough. It seems to me that I had a fuel injector not working so I bought three remanufactured injectors from the internet. I replaced them and it seemed to be perfect. when I test drove it it ran better then it has in years. I got it out the next day and its back to not running. I took the lock clips off the injectors and took off. When I unplug number three there is no change. I swapped number one and number three and the problem followed the injector. I changed ou the good injectors from before and it still wont run right. I put a fuel pressure tester on it today and it bounces between 35 and 40 while idling. Right after I shut it of it goes to zero within a second or two. Can anyone help me with this I just cant figure it out.
