So my Sprint has been a bitch to drive for ages. The fuelling has been all over the place and it's had a missfire on cruise.

my lean off is blocked but its misfiring at cruise, its going down to 11.5 afr and it never used to. so i might connect it back up and see how it goes. |

That's why we have a pair of small maul grips in the van's door pocket. Instant part throttle lean of clamp On 11th Feb, 2015 robert said:

So my Sprint has been a bitch to drive for ages. The fuelling has been all over the place and it's had a missfire on cruise. I've tried lots of things but no change. today in a desperate attemp to find the problem (and thinking that cruise was the worst condition) I blocked the part throttle lean off pipe. It's like a new car. fuelling spot on, propper boost, lovely jubblie. And to add the this I found my I-pod while scrabbling around trying to find the screwdrive I keep in the car for tinkering. Anyone else had issues with the part throttle lean off not working. The link pipe was in perfect condition btw. Possibly the drilling from plenum to chamber is blocked or something. 9.85 @ 145mph

Mine would never run right with the part throttle lean off. The moment it was blocked off it ran perfectly. On 15th Jul, 2009 fastcarl said:

I know you own pretty much every set of grips in the northern hemisphere but these ones actually came from my house when I spent the weekend tuning the van pre-avon last year.

its hard to get the mixture spot on using the lean off pipe, with some engine configurations its all but a pain to sort

How about adding an aquarium valve inline so the part lean off is adjustable,

If it worked then a solenoid would be a good idea. Fastest 998 mini in the world? 13.05 1/4 mile 106mph

If you have megajolt or similar you could easily control the solenoid based on manifold pressure - vacuum open, boost closed. |

It goes all over, completly inconsistant AFR. On cruise it just backfires, then fuelling stabilises then does it again.

maybe vacuum pulses in the lean off pipe are causing a problem. Or just a sticking valve? |

Hence why it took me months to even try blocking it. Obviously it's a long time ago. And I had no plenum restrictor. But I never had any issues, and I always had the lean pipe installed. That said, there were no such thing as widebands back then, so n idea what AFR's were actually like. But it wasnt particularly hard on fuel or anything. I guess whether it is installed or not hardly matters as long as the end result is the car diving nicely. But for the above post saying he is seeing 10.0:1 AFR on cruise, that is ridiculous. That is a major problem that needs sorting. Whether by lean off pipe or a proper needle to suit. 9.85 @ 145mph

Really seems to differ alot with different configurations, some have fueling troubles where it lean off pipe needs optimising or removing, others (myself included) dont have any trouble with it. Tested mine on the rollers did not make any difference weather it was blocked or not. -MINI CLUBMAN 1380 TURBO- |

You could try putting a restrictor in the lean off pipe, as per turbo phils site......
