Hi All.

Got a interesting fault here.. Its easier to show you rather then explain it.


The fault is not present at idle, only at over 1000 rpm. Other then this, the car runs fine. When checking measuring blocks for voltage in Engine its about 13.8 then give it a few revs and we lose communication. The headlights, interior lights etc all work and don't flicker. I have check the battery voltage at the battery and ignition switch, I suspected the voltage would be low, but have a steady (on an scope) 13.9v at the battery and after all the fuses and at ignition switch. No dropping out.

Here is the before scan:

Nice post; a picture is worth 1000 words and a video is worth 30 pictures per second. :D

Diagnostic comms to the engine (and only the engine) go THROUGH the cluster, so I guess it's not a surprise that you lose comms to the engine when the cluster loses its mind.

As to why the cluster is losing its mind, well... If it were me, I'd start by pulling the cluster out of the dashboard far enough to probe the connectors on the back of it and verify power and ground at the there. A 'scope is an excellent tool for that.

So I scoped the power supply to the cam sensor and injectors, had massive spikes in the pattern, eventually traced the fault to an earth for the coils that hadn't been put back on properly after someone had replaced a coil! Put that back on hey presto, we're done.

Nice work! I wouldn't have known where to even begin on that.

Blessed is the Auto-Electric guy who has an oscilloscope and knows how to use it. Far too many people these days think a scan-tool will do everything they need. They're wrong. Scan tools are obviously indispensable on modern cars, but they can only tell you what the car itself knows, and it simply doesn't know everything.

It is seriously recommended because the VC is pot metal aluminum........... a poor conductor by all standards through a cast iron block.
Run a ground directly to it for that lug for coils to the battery......

It will save your coils later and is most likely why someone needed a coil............enhance them all if you can.

That video is awesome and looks like a pinball machine hitting the jackpot.
