(3.0si, auto, 103k, ~250 miles a week)
I've had a couple of intermittent cases over the past 2-3 weeks of juddering and loss of power on acceleration (around 2k revs), triggering the exhaust emissions warning light. Normal running for the rest of the journey and the dashboard light turns itself off after 10 minutes.
I've felt a slightly less severe version of the juddering a couple more times this week, but seemingly not enough to trigger the warning light. Recent MPG is around 35 and that's stayed pretty steady. It doesn't seem to occur if you drop a gear before accelerating and it hasn't happened with sport mode engaged. Oddly, felt a slight judder when reversing near the time the issue first happened properly.
From what I've read (people experiencing similar symptoms constantly), the main causes seem to be: ignition coils, an air leak or lambda sensors.
I'm a bit hesitant booking it into a garage without a constant dashboard light (presumably no error code to diagnose) and I've already spent a significant amount on issues/repairs. It's a daily driver, so it's tricky if my garage doesn't have a courtesy car available and I may need to hire something if the Z is in the garage for more than a day or 2.
Just checking your thoughts - is it Ok to continue driving as is and book it into a garage if it either gets drastically worse / more frequent or is still happening intermittently after a couple more weeks? Or should I get it booked into a garage now and (in leui of a dashboard light) specifically ask them to check the ignition coils and for air leaks (and failing those options, lamdba sensors)?
