I know it has to be in the 10-14ohms but im baffled that my 7.7 Ohms injector is dead and the 17.74 is working! what is going on here? before i go and buy an injector can you guys help me out? before this it was running on all six. after i sprayed down my injector with electric connector cleaner in a can and brush it with an iron brush to knock of all the rust down. then i hosed it down again with electric cleaner then i used a paper nail file to remove the rest of the rust. THEN i added electricl dialect gel on the injector connector. now BOOM #3 cylinder is dead. car idles rough and running really rich.

The 7.7 is stuck. The 17.74 is on its way out. They're out of spec, and the car is running rough. Replace them. I'm also moving this to tech.
