I have a print-out of an 'MOT Emissions Test' from August 2002. When all cars being tested were either Euro1 or Euro2 emissions standard. The 'Fast Idle' CO limit was 0.3%, and 'Natural Idle' CO limit was 0.5%. With the advent of Euro3 or Euro4 emissions standards, The MOT Emissions Test became more...

Does the 'Check Engine' warning lamp stay on when the engine is running ? If yes, it means that there is a fault code stored within the Engine Control Unit. If not, it could be an ignition problem ( which does not switch on the 'Check Engine' warning lamp ). There are two ignition components on this...

What are the 'Emissions Results' for your car?

For a 'non-catalyst equipped vehicle', the MOT limits are CO 3.5% and HC 1200ppm.

Haynes Manual 3344 - Engine Management and Fuel Injection Systems - has a whole chapter on the Honda/Rover PGM-Fi System, and also on the Rover MEMS MPi and SPi System. It includes detailed descriptions of each component and how to test it, overall description, drawings, diagrams and Fault Code tabl...

I have replaced the Ignition Coil and the problem is fixed. The old Ignition Coil had only been on the car for 13 months and covered only 300 miles. Maybe when the old Ignitor Module failed, it overheated and damaged the Ignition Coil ? The Ignitor Module I fitted, came with a sachet of Thermal Grea...

Yes, the car drove well when cold. But I have only driven it once. Will have to check that again. Replacing the Igniter Module cured a much worse missfire, so the old part is no good. Replacing the Ignition Coil also cured a bad missfire, so that part is no good. The Rotor Arm has not been replaced,...

Thank you for taking the time to ask these questions. When engine is warm it revs, but stalls under load, however it goes when using high revs. I replaced the Ignition Coil a year ago which cured a similar missfire to the one I have now, but was also when engine was cold. I have only driven the car ...

The problem started immediately after fitting only the new Ignitor Module, but it was not evident until the engine warmed up. I had an even bigger problem beforehand which prompted me to fit the new Ignitor Module: the engine was missfiring very badly, so that I could only drive the car at walking p...

Hi, I know exactly what is going on with respect to your engine running rich, and your mechanic suggesting you change the o2 sensor. pre-cat cars do not have o2 sensors, nor do they have catalysts connected to the front of the exhaust pipe. your mechanic does not know that your car is pre-cat, other...

216 R8 Honda D16 Engine pre-cat. Engine wants to stall when attempting to move off or change up a gear when driving, when it is warm/hot. It is possible to drive the car using high revs when warm/hot. But the engine works perfectly when cold. I have recently fitted new Ignition Coil, Igniter Module,...
