Hi guys

Just took the Tuscan out of the garage, however it took a bit more cranking than normal to get it fired up. The engine would fire and then die. In the end I had to give her a blip of throttal to get her started under her own steam. Is this normal or is it a sign of a sensor playing up? I only took her out yesterday to give her a clean and was running fine then.

Should start on no throttle and idle at 850-950 ideally

Usually a low cost interim service will fix it.

Do mine every 2k miles for me just to keep it spot on

What is this low cost item that you do every 2k G?

Aye I would like to know as well. Shes due for a 24k mile service in 2k miles time but may get it done at the end of the summer for peace of mind.

I think this is another "they're all different" question. My 3.6 has always needed a little throttle to fire immediately, after which it idles like a pig for the first minute at about 500rpm if you leave it to its own devices. When it's hot the idle is around 700 rpm.

I asked Fernies about this at the last service, and the response was that there's no cold idle enrichment on the Speed 6, so it's a trade off with easy starting and then having warm idle too high.

My solution as recommended by Fernhurst, is to start with minimal throttle then hold the revs at about 1200-1400rpm for 30 seconds. After that it idles very sweetly. Incidentally, my compression and valve clearances are all very healthy, so it's not a work-around for a b*ggered engine!

Cheers,
Pete

Best just get your 24k done early and enjoy the result!

Just to clarify on mine every 2k regardless do full oil & filter, air filter and diagnostics throttle pot reset inc idle adjust 850-950rpm and no throttle needed to start, hence does not stall.

Peter Smith & Power do interim servicing

Agree with Graham on this one - my Tuscan was doing the same. Had the throttle pots reset and that sorted it out.

It's recently started doing it again, seems to be after being driven in heavy rain of maybe just a coincidence. Once I get a laptop and syncrometer I'll be checking it myself every couple of months to keep it running sweet.

For further info, to restore an idle speed that has just fallen 100rpm or so from the settings at the last service - which happens every time after a few thousand miles to me! - you're ok to do this as a quick easy job adjusting the throttle stop position.

Just undo locknut & then use an allen key, clockwise about 1/8th of a turn. smile

I have always been told to start the car from cold with a small amount of throttle and have always done so in all my Sp6's. (I think thats what the manual says too?)
