sparky Posted December 20, 2014 Report Share Posted December 20, 2014 Hi fella's, Changed the fuel filters on the boat, bled the system, but now the engine is ticking over higher than normal, can anybody shed some light on what could be the matter please ? Been down again today, bled the system at the fuel filter but it still the same ! Any advice would be appreciated. Thanks in anticipation.

Rob Posted December 20, 2014 Report Share Posted December 20, 2014 Maybe it depends on what's normal? What does the book say? Sure it wasn't ticking over too low before the change? Quote Link to comment Share on other sites More sharing options...
sparky Posted December 20, 2014 Author Report Share Posted December 20, 2014 It has always ticked over at 750 rpm which is correct, but it is now ticking over at 1100 rpm and starting up at 1350 rpm which is way to high ! Any idea's Rob? Mick Quote Link to comment Share on other sites More sharing options...
niggle Posted December 20, 2014 Report Share Posted December 20, 2014 May be you've knocked the throttle linkage,check it's going back to the idle stop? Quote Link to comment Share on other sites More sharing options...
sparky Posted December 20, 2014 Author Report Share Posted December 20, 2014 The only throttle linkage stop I can see is the ECU under the seats , I cannot see one on the engine ! If there is one Nige, could you point me towards it............or is it controlled electronically by the ECU.? Is there any linkage attached to the turbo from the throttle cable ? Thanks.

sparky Posted December 20, 2014 Author Report Share Posted December 20, 2014 Would an air lock cause this kind of problem Nige? Quote Link to comment Share on other sites More sharing options...
niggle Posted December 20, 2014 Report Share Posted December 20, 2014 Unlikely air in the fuel would give you a high idle,is yours fly by wire throttle then? Quote Link to comment Share on other sites More sharing options...
sparky Posted December 20, 2014 Author Report Share Posted December 20, 2014 Don't know....the only throttle cable I can see goes from throttle control through the engine bay and back into cabin where it connects to the ECU. Move throttle and the cable moves the lever on the ECU ,which is where the idle stop appears to be and it is touching the stop . The gearbox cable also runs from the throttle control, but can be disconnected by pushing in the red button on lever Cheers Nige Quote Link to comment Share on other sites More sharing options...
sparky Posted December 28, 2014 Author Report Share Posted December 28, 2014 Trapped air was the problem, my mate bled the system by cracking the injectors, running fine now, but going to give it a run onTuesday to be certain, thanks to those who replied !! niggle 1 Quote Link to comment Share on other sites More sharing options...
