Towed in as a no go.hHas fault code for exhaust cam sensor. Sensor has been replaced. Fault code still present.

At this point i got involved and scoped the crank and both cam sensors to get all signals present and correct.

The coils are being triggered,the plugs are wet and its got compression (160+).
When its 1st cranked it fires slightly or pops through the manifold on occasion so am starting to think its a cam timing fault.Would imagine I'll need tooling to check this.

Sound familier?
