The fact that it is fine when warm suggests it is a fuelling issue, My thoughts are that it is not adding the extra choke fuel on initial start up. When you say the ETS is ok do you mean you have replaced it or just that there are no fault codes?
I would clean out your throttle body, checking for corrosion or deposits. If the answer to the above question is "no codes" then get a new ETS. I would imagine this is not hard to start from hot? |
I have monitored the ETS carefully with diag tool and I'm pretty sure it's OK. That is the first thing I thought too (see first post).
From hot or even after a succesfull start running for a few seconds, it then fires-up straight-away perfectly every time.
Throttle body looks in mint condition, no corrosion and butterfly seems to be opperating smoothly when pushed with finger (2007 car).
It's a puzzle.
Could it be the actuator of the TB is problematic..

'Will check Lee, thanks.
I don't think it's an earth issue tbh though. I'll see about the pressure and double check anyway.
Could the previous owner have mapped it and could this be causing this?

You're welcome to anytime.
Lee said he would but hasn't got round to it.
Maybe he is afraid of the current situation over here. Anyway, different topic for that in a few months time..

Update:
Just checked with live data, I only seem to have "FUELSYS:" which says OL with engine off and CL when engine
is running. No pressure reading parameter anywhere.
But leaving the key in the ON position for a while before starting, made no difference whatsoever. Hessitant again.
I should point out that the behaviour of the slight jolt (see link in first post) is still there after all these months. Could this be connected I wonder?
Question: Am I right in thinking the Oxygen sensor (1st, pre-cat) is ignored at start-up until the ellement is warm?
Otherwise, I have here an OK sensor from when I replaced mine a while back, worth giving that a try?

My car does this when cold and runs fine after clearing out the cold air through the system.
I have found that she does not like cold air being rammed up her grills.
We had a oxygen sensor replaced a while ago i can't remember if it was like this then but its always been their as far ass i'm aware but the wife did have major issues with it a few winters ago when it was really cold and wouldn't start for quite a while.
Good luck

The ones coming-off the battery onto the chassis, gearbox etc are tight and fine for sure.
Engine temp sensor is also fine by the readings from the diag tool.
Is the O2 sensor ignored at startup?
What is 'FUELSYS:' parameter OL and CL anyone know?
P.S. Lee I think you just broke the site.

CL = closed loop
OL - open loop.
No the one from the ECU to earth

What there is a strap there? Apart from the 3 connectors?
Will check ASAP.

There are about 5 earthing points under the bonnet. Near both front lights, strut (battery side), gearbox, crossmember, maybe a few more.
Take a look at the connector on the ECU and see where the earthing point is.
I'll try and find it
