Not sure what else to try. Any ideas would be appreciated. I have random misfire codes P0301 or P0303 or P0305. I have tested the coil resistance on all the coils. They all read .9-1.1. I have one coil that reads misfire and I have moved them around i.e. I had a code on 1 so I moved it to 3. Then i had a misfire on 3 so I moved it to 5. Then I had a misfire on 5. I thought I had a bad coil pack so I purchased a new one. At that point they all tested the same resistance but I continue to get a random P0301 after I reset the computer.

I have changed the fuel pump, no coolant leak, changed plugs, knock sensor, air filter, checked manifold, VIS motors are good, no rattle.

Thoughts??

 

Injector or manifold gasket
