Already replaced the lambda sensor but have another one that I got today.

Also got a second hand fuel pump.

Both getting fitted tomorrow and hopefully that's the end of it all!

Would there not be a code regarding spark etc?

Don't see it being water as the car goes. The fault is intermittent.

Yesterday it died on me. When it revved it was really struggling but after a 10 min break it cleared itself.

These 2 new bits better fix it!
