I changed the autobox a while ago and due to that took off the exhaust. Couple weeks after the autobox change and ever since till last week had some rough idle on coldstart and also smell of petrol. So I looked up for the reason and the other (Cat to manifold) gasket had somehow broken. Now everything is fine. Just to let you know... :)

On the v6 it is easy enough to get the ecu temp sender and purge valve plugs mixed up. The ecu sensor is 5v, the purge valve is 12v, and putting 12v through the temp sensor really pisses it off... car will start once from fully cold but assumes that engine temp is -40°C and dumps the fuel rail at each subsequent starting attempt, flooding it spectacularly.

Quite why the ecu would allow it to even crank with a coolant temp of -40°C remains a mystery...

That's a worthy note for this thread / future generations to read. Again, quite why they'd make them the same plug, and so easily mix-up-able is also beyond me.  :)

Using standard, commonly available connectors is actually good design. Temp senders, bulb holders, fuel injectors etc all use the same generic connector, and new replacements are readily available at very  low cost. Different colours, matching the component are a good idea, but maintenance in this area is rarely needed.

I do like and approve massively with the logic - my gripe is just in this specific area, that's all. Even with a set of clear instructions saying 'don't mix these up ever ever ever' in a Haynes/Service Bulletin etc it still leaves it open for even someone attentive to become distracted/walk off etc... then mis-remember which went where. A spot of coloured paint. even, would cure this, that's all.

But I'm all for economy of scale / common parts used all over the place / on other cars, the same parts used for various different jobs, and so on, definitely.  :)
