rough running

So I have a 2000 156 2.5 v6 and as the title says it running rough. So far I have replaced oil and filter, fuel filter and pump, air filter, air intake hose between maf and throttle body, crank sensor and lambda sensor. I've done ecu and throttle body reset and still no joy. The oil breather pipe at the back of the engine was loose so put new clip on nice and tight. Everytime I fix something car runs OK for about a day then the problem returns. Tried to connect an ecu scanner but it wouldn't connect. I'll try another one when I can but does anyone have any ideas about this that could help. Vid here https://m.facebook.com/groups/662842...96774287071372

Silver GT 3.2 V6

I was on holiday in France a couple of weeks ago (Normandy and Brittany) and my GT 3.2 was running a bit rough during the holiday. We got back to Calais and stopped at the Cite Europe shopping centre to stock up with wine before coming home. Got back in the car and it would not start. Called breakdown cover and after a short wait a very nice French breakdown guy advised the battery had died. He started the car using a booster pack and took us to 'French Halfrauds' who sold me a Varta battery and fitted it for a very nice price (for them!). It's now like driving a different car, so smooth and powerful. We were in France for two and a half weeks and I had no warning apart from the windows playing up a bit, the car had been starting fine. It may be worth looking at the battery and at least giving it a charge, and if its a few years old it may be worth replacing.....

Think it might be something to do with the injoctor loom. I've downladed multi scan just waiting on cable being delivered now

Well cable came there was loads of faults stored. Cleared them all as I didn't know how old they were. So far hasn't misbehaved 😁
