1990 Ford Sierra GLS 5 door 2.0 DOHC EFi
Summary:
Reliable and quick family motor
Faults:
Very few problems, only major expense was MAP (manifold absolute pressure) sensor blew causing the engine management system to go awry. Not a cheap part -> £150 from the main dealer and not the sort of thing you want from a breakers yard.
Other than that, just servicing. Engine needs a tune and the timing chain probably needs changing again (should be done every 50,000 on this engine).
General Comments:
Loads of low end grunt, gets harsh over 4,500 rpm, still a quick car.
Good levels of equipment and comfort.
Not as good as Pinto engined cars for modifying, but 170bhp is possible for under £1k.
Would you buy another car from this manufacturer? Yes

I have an identical problem with my 1990 2.0i Sierra, not a bad purchase for £20 but cannot figure why idle is so erratic. I've disconnected the throttle control valve, changed plugs and HT leads, but it's still erratic. Sometimes car is fine, other times the car will stall all the time if throttle is not depressed. Has anyone got any ideas on how to rectify this (apparently common) problem?
