Problem resolved...for now

The dealer swapped out the ECU and the engine no longer would start. I had warned him of this, but the dealer told the shop that this car should not have the security system.

I get the same results as you. I am testing with coil packs out of the engine. It shouldn't matter whether the coil is in the car or not, since the coil only contacts the plug electrode and does...

If you go to the effort of replacing the valve covers, you'll also want to replace the PCV valve and probably the intake manifold gasket. And perhaps most important, clean out the EGR tube.

Any help on how to remove the hoses back by the EGR tube would be most appreciated. I believe that's the last items I need to remove now.

more on plug seals
