zygott Posted January 8, 2018 Share Posted January 8, 2018 my 1990 cabby keeps randomly stalling. as i am braking for the lights/junction sometimes it stalls, others the revs drop low, (oil light comes on then goes out), other times its fine. can be when im on a dual carridge way, or round town. when the engine is hot, or after 5 mins of driving. have cleaned the ICV, then changed it for a spare and its still the same. any ideas? its an XR3i EFI, has aftermarket airfilter and sportex exhaust with 421 manifold on it. runs perfect just suddenly stalls when you put the clutch in. i can bump it while rolling and it kicks up straight away. (literally lift my foot off the clutch and press is straight back down and it will struggle to idle) just a quick blip of the throttle and its fine, its as if the car does not know its supposed to idle and when i blip the throttle it realises im idling and not driving so works fine,. if i manage to stop at the lights ok it will sit there and idle all day long, never stalls then, its only when i press the clutch. probably 6 out of 10 times it stalls. i now have to press the clutch then quickly blip the throttle before braking and it doesn't stall then, not good at 60 on a dual carriage way approaching lights/round about!

StuDaBear Posted January 8, 2018 Share Posted January 8, 2018 I would start by cleaning the throttle body out with carb cleaner. Quote Link to comment Share on other sites More sharing options...

Stephen Bearded Minky Hill Posted January 9, 2018 Share Posted January 9, 2018 If you unplug the iscv does it still tick over around 750rpm? If not the "base idle" needs setting. There's a small screw on the left of the throttle body near the tps. Quote Link to comment Share on other sites More sharing options...
zygott Posted January 9, 2018 Author Share Posted January 9, 2018 if i unplug icv it stalls. changed base idle a bit and seems loads better. revs dropped a couple of times but not stalled. Quote Link to comment Share on other sites More sharing options...
Paul Grainger Posted January 20, 2018 Share Posted January 20, 2018 If the Base idle and fuel mixture it set ok then you look at the speed sensor on the gearbox. Is it connected? This should hang the revs up momentarily whilst stopping. They usually get an internal fault which makes the tick over fast and people disconnect them instead of replacing them.
