So after much work sorting out many previous bodges and incompetent work on my 2009MY TD4 manual box SE, he was ready for his MOT.
It still has a slight misfire under heavy throttle, which is more pronounced when cold, but otherwise its driving fine.
So this morning I drive him to the MOT, stopping at CoOp for milk on route.

On returning to the car, the engine started just fine, however when I went to pull away, I discovered that throttle didn't respond on the first, second or third press. After which it responded, although it now feels like there a slight delay between pressing the pedal, and the engine responding, not much of a delay, but noticeable to me.
This is a new fault, which I've not encountered before.

Hopefully the MOT goes ok.

Any ideas as to whether this is a common issue, and if so, what is the cause.
Obviously I could do with some good behaviour from him, after many months of repairs and undoing the dozens of bodges I've found.

I used to get that on mine if I stuck it in gear too quickly after starting, almost before the starter motor had disengaged! Past: FL2 TD4 HSE Auto

Thanks for the reply. It's not done it since, and it passed the MOT too, which is good. Hyundai Ioniq 5 Ultimate. The family car.
