I have 2 cylinders that are not firing. I did the spark connector test to locate. I then did the screw driver to listen to the injector. Both are not firing. I pulled the plug off of one injector and put an ohm meter to it - it should an open circuit. My question is that could the injector be good and just showing an open issue if the injector is clogged? My tt is a 91 with only 23k miles. It sits a lot obvisously - i ran it every month until i moved and couldn't get to it as often... that is when I started noticing the issue.
Could that cause the ohms reading open? Do you think I can take it to a shop to clean the fuel system without removing the injectors?
