Will do. Do you need to see the actual temp logged or just that I warm it up first?
You could add it to the log however all I need to know is that the engine is up to temperature. 15 minute running it should be enough.

One more observation from you.

When you start it up from cold, how does it idle ? Is it normal and smooth ?

Nothing out of the ordinary noticed, but I’ll check again when I fire it up next.

Pretty sure the FPR is fake. Took it off to compare it with a known good genuine one and there are subtle differences, whether they are correct or not is for another day and a discussion with the seller.



Anyway, the genuine Bosch FPR was fitted, I warmed it up and prepared the values for the test drive, took the same route as before and it pulls like a train. Graphs as below…



So it’s been a great learning curve and I know a lot more of what information to post up in future. Thanks for all the assistance, and while I’m sure Dr Sheldon will tell me it’s more luck than judgement, I’m in a pretty good mood so have at it.

I’m now going to pour 75ml of Arran into a glass and drink it at a rate of 25ml/5 minutes.

Thanks again.

So it was a lazy FPR after all. Interesting, and good to see you got it resolved. :thumbs:

The last bit was the FPR, the show stopper was the injectors. Cheers again.
