FridgeFreezer Posted April 30, 2021 Share Posted April 30, 2021 Welcome! Have you removed and cleaned the idle air valve stepper on the back of the plenum? Quote Link to comment Share on other sites More sharing options...
teabag Posted April 30, 2021 Share Posted April 30, 2021 Welcome to the forum. Engine stalling can be a result of a very dirty/blocked crankcase breather (flame trap), so remove and clean by soaking in petrol also check and clean, if required, the pipe to the plenum chamber.
