usual things apply... . but you seem to have done them all... might be worthwhile unplugging the ECU and spraying a bit of WD-40 or the like in there. its *possible* the lambda is failing, how long since it was changed? i think rover specify a change schedule for that?
before you change the lambda, be sure and try get the errors read by a fault reader though.

SPi is fitted with a manifold heater for when its cold which is controled by the relay box.Could be afaulty heater or relaybox.

my manifold heater hasn't worked for about 4 years, only on the *coldest* mornings did i notice it. mind you changing gear on those mornings was tough too... a sump heater might have been a better idea!


i wonder if the car is running rich or lean in the flatspot, or could it be a timing issue. does it hesitate, spit back, bog down, misfire??

A common problem with thoes is often the plug not the sensor itself.
