172 running fine and then terribly, out of ideas.

This car has been doing my skull in for a while now.
It either runs spot on and flies along or runs like absolute s**t, barely idles, struggles to pull away and generally feels like it's about to breakdown any second. There's no rhyme nor reason or predictability to which will happen on any given journey.

Rather than saying what's been done to it already I'd like to show the values that are coming up and you can throw an opinion my way.

lol, honest to god she tells me off more than my wife does 😂😂

428s or something like that. I did cross my mind but ruled it out as it's so intermittent.

I would but it's defo broken.

As in I wouldn't rely on it for any journey that I'm not happy to walk back from.

which reminds me, it also doesn't start first time. If it doesn't start first time then chances are it's gonna run like s**t when it gets going

mine sounded like that on the back of 2 problems. One was the lambda, only a genuine Bosch sorted it. The 2nd which was causing the cutting out was too much vacuum. Created a small vac leak and that solved it.

Two fairly easy options if not already tried. When it’s being a dick try and unplug one of the vac lines and use your finger to control the air getting in and see if it improves

If a vac line is pulled and it helps , then it’s running Rich .
Poss a lambda issue .

Try disconnecting the primary lambda sensor and run it in loop mode and see how you get on with that .

Well, some more data reading today. Had the lambda stream up and when running well it's within spec. When it's running s**t the primary sensor is up at 2.5v

think we might have a winner. Will get it changed and report back

Clio's like to eat lambda sensors.

Probably more so if it's not mapped for the cams.

I bet when you remove the old sensor, that it's more coked up than Danniella Westbrook.
