94 SPi - running a bit rich

Normally this would be the lambda sensor in the exhaust downpipes. Make sure the ehxaust doesn't blow anywhere aswell tho. Does the choke work ok from cold. It should go to around 1100rpm ish if I remember rightly from cold then settle at 850. You dont say what yours idles at on cold start.

Are you sure it's not a good old-fashioned misfire? What's the performance like otherwise?

Cheers,

Lambda confirmed as OK in this afternoon's fault code test, as did the rest of the sensors. Turned out to be a split pipe boot on between the back of the inlet manifold and the fuel trap which goes to the Manifold Absolute Pressure sensor in the ECU.

Quick trip to the scrappies to take a look at some SPi Metros resulted in a couple of spare boots; one for now, one for next time.

Pretty sure. Started fine and ran beautifully when cold, as it warmed up the idle speed was getting lower and lower until it bottomed out at about

Before it came off the road in May, fine except for a lack of power but no misfire around 3500rpm. No MOT at present, so only able to take it up and down the drive. Wheelspins in 2nd once warmed up though.

As previous post, now resolved.
