Firstly ---after replacing the camshaft sensor the no code senario became
I have a misfire on cylinder 6 ---p0306 so the camshaft sensor was bad ie multiple partial problems on ignition system !!
plug #6 looks very good but --------- dark colored
other plugs are ok and slight grey- jeep runs on 5 cylinders roughly
no codes for the injectors
I have found that testing the coil rail the resistance should be 15k ohms for the plug side
as I understand it one coil should on the plug side activate 2 plugs - once on ignition , once in the exhaust
There is also on the primary side a plug with 4 pins on the rail - input
I assume one of these plug pins is ground for all the coils the other three pins activate each of the 3 coils as required by the switching transistor or camshaft sensor ?
right so far?
what value should show up on the 4 pin primary side of the coil rail?
ie ground to each coil bank ?
were is the best place to buy a coil rail - dealer , parts place ebay ?
gotta check the compression on cylinder #6
