My 1.4 ie failed the Mot on emissions - tester had never seen them higher at about 9.1 (should be <0.something).
History is that after driving through a very wet patch of road a couple of months back it developed a chronic misfire. New plugs, points and leads failed to cure it, found to be timing, so had new cambelt fitted - ran fine, but consuming way too much fuel. Gave it a treatment of injector cleaner, still no improvement, so put in in for early test to see what else it failed on, with a view to fix if cheap.
It starts and runs fine, except it's doing 25 mpg driven sensibly, on medium runs.
Is there something I'm missing here - say ECU failure? Seems unlikely that the timing is/was incorrectly set (by a professional), given that it's otherwise running acceptably.
Another forum has suggested checking the map sensor, cts, lambda (wot's a cts..)
