Hi,
I can't say I have ever noticed what RPM I change gear at. What RPM would you suggest I changed gear at? Have been driving for 25 years if that helps - not a boy (girl) racer.... |
Hi Kay,
So what rpm do you change at very roughly?
Ofcourse, it highly depends on the load to the engine: uphill, level road, gear etc.
But next time you're in there, have a feel for the engine sound at which point you shift naturaly and see what the rev-counter says.
'Not saying you're not a good or experienced driver under any circumstances, but it could be linked to an actual fault.. Also, what was the previous car exactly?
For testing purposes alone, it would be worth trying to conciously shift at a much higher rev range overall and see if that makes any difference to the symptom. |
I would say I never go over 3200 revs and changes are probably at about 2000 revs

Common issues causing warm start problems are the 3 following sensors :
Coolant temperature
Crank position
cam position
I had this issue, swapped the sensors in the above order, was only when I installed a new cam position sensor was the problem resolved and it then started fine every single time from then on.
That sensor was thought, I beleive, NOT to be used during the start-up process but it was certainly the one that did it for me.
If I recall, when the problem happened for me, if I unclipped then put the sensor back on it would often clear the problem.
Googled, and found this clip for you.

That sounds like the throttle body and 'the sensor' would be the ICV?
However, if it's small black and slightly to the left it's the MAP sensor (possibly with integral intake temp sensor in it).

the sensor that was replaced sounds like this, and i have to move the cable down its connection and push it back on. the connector looks clean

OK that makes sense, is the connector something I can open and fix, or do you mean its broken anywhere down the electrics, and likely to be a massive labour cost to replace?

Just a thought, if its a broken connection, why does it start PERFECTLY when cold?
Just trying to understand...

Well it's obviously difficult to describe off the top of your head about this, and there could indeed be a sensor issue.
Definately worth shifting a lot later as a try, and keeping the revs highish to avoid labouring the engine.
This actually makes it work less not more, and doesn't over-fuel the cylinders come next start-up time.
Both me and my other-half had this issue at the begining even though I've been on the wheel for 20 years too.

I will try this when I am out working tonight, after all it's certainly one thing I can try myself. I am very grateful for all the suggestions.

Youll need to use a pic host like photo bucket and copy and paste the image code here to upload a pic
