Good timing

So the Griff has been faultless recently except today when I ran it to the petrol station to fill it up for the run to the chunnel Friday morning.

It stalled twice when I came off the gas during the journey. Restarted and drives fine so is stepper motor the main suspect there ?

Is cleaning a good option or is it like pesky EGR valves, one they start playing up cleaning is a short term measure ?

thanks

Head over the parapet here, but do TVRs even have EGR valves? News to me.

Yep, you should clean the stepper because it just gunks up and gets stroppy.
It's a simple job, just wrap the threads with a bit of plumbers tape when you put it back together and watch how far it is in now and put it back to the same depth of threads. That way you can be sure you won't crack the casing it fits into by screwing it in gorilla tight

The comment about EGR was related to the Saab diesel we have. You can clean the EGR but replacement is the long term option

Sounds like the perfect opportunity to test your new app and start working on your background logger.

Seriously, are you getting any fault codes? Also check the target idle green light comes on in RoverGauge.
Good Luck

No fault codes reported by my app - but i'll fire up Rovergauge tomorrow to verify.

I'll whip the stepper out to see what it looks like. I note that the ecu has no feedback from the stepper, it simply winds it fully one way then counts the steps. doesn't actually know if its moving apart from using engine rpm etc as a guide.

When you fire up RoverGauge also check the corrected throttle drops to 0 %, unbelievably the max is not so important.

So I cleaned the ISCV last night, but have to say it wasn't very dirty.

I fired up rovergauge - without the engine running, and no foot on the gas, Rover Gauge showed throttle at 5%.

Is this what you meant to check stevesprint ? Is this a problem ?

FFMan if you select the RoverGauge Help/Contents... command the Help screen is displayed. Scan down to Throttle position: where the Absolute and Corrected select buttons are explained. With Absolute selected at rest a low positive value (5% in your case) is shown, if Corrected is selected the reading will show as 0%.

Good luck with your Android/Bluetooth app BTW.
