should i get an increase in ohm readings on the ground system with the key on?
testing and repairing all the battery grounds, to engine, body, and all the sensors themselves. with key off i am getting little to no ohms from battery neg to engine, body, and all sensors, telling me i have good grounds to each. with key on i get an average of 5 to 6 ohm increase at all sensors, and 3 ohms from bat neg post to engine. even if i pierce into the 2 awg neg cable 6 inches from the post, i still get a good 3 ohms resistance. key off everything is great. chasing a low idle issue and it seems the ecu is telling itself to lower the idle after a few seconds of run time. all sensors test good and most are new.
