My 1992 1360cc Citroen ZX - Stalling, Rough Idle etc.
Discussion
Wondered if anyone can help.
The engine runs fine when cold, but when warmed up, starts to idle erratically, stalls, and cannot maintain a rev range (e.g. hold the throttle at a position, the engine lurches around).
I have replaced the spark plugs, ECU, coolant sensor (x2 - one for the guage, one for the ECU I suppose), Lambda sensor, fuel injector [it's a monopoint injection].
(Thankfully all of the above off a donor car!)
I do not think it's spark related: when cold, or when warm and being 'good' the engine revs fine and pulls as good as it should.
The symptom seems fuel-related: it's not metering the right amount of fuel, or related to a sensor to meter this...
I'm looking to replace the entire unit [Bosch Monopoint MA3.0], as this includes the fuel-pressure reg. and the throttle position sensor, both which can't be changed independently (easily).
If anybody has any other clues to check, or had this before, would appreciate the feedback...
