kdowg Posted April 7, 2011 Share Posted April 7, 2011 rite I've just changed my engine over as the last one wosnt running so smooth and just didnt seem healthy at at. it also misfired between 3000/4000 revs.so i changed the engine over but i took the the inlet, injectors off the old engine to pput on the new engine and the strange misfire is still there only between 3000/4000 revs on a whole tho this engine is in a much better condition and runnin sound apart from this strange bit.now im starting to thing it must be a fueling problem (as i had already changed all of the ignition side on the other engine) just wondering if any of u guys know wa it could be and if any one has had a similar problem ?also when it starts misfiring the dash boost gauge(the three lights) the very first light flickers on and off only when its misfiring tho then stays off after im past the 4000 rev mark (the three lights dont work either just the first one when its misfiring)any help will be great as this has my head in bits lolcheersdan Quote Link to post Share on other sites

micky boy Posted April 7, 2011 Share Posted April 7, 2011 When new blue owned the car befor you i always said to him i thought it might of been the ecu as he tryed everything to get rid of the misfire but never did so maybe try a diffrent ecu and go from there....Also are you sure the leads,plugs ect are ok? Also have you done a diagnostic test to see what it brings up? Quote Link to post Share on other sites
kdowg Posted April 7, 2011 Author Share Posted April 7, 2011 Mine did this, was the king lead earthing on the FMIC pipe.. just a suggestionits still got a top mount on it and I've checked its not earthing on anythingWhen new blue owned the car befor you i always said to him i thought it might of been the ecu as he tryed everything to get rid of the misfire but never did so maybe try a diffrent ecu and go from there....Also are you sure the leads,plugs ect are ok? Also have you done a diagnostic test to see what it brings up?I've changed the whole ingition system and no luck. hmmm wud be handy if i could get hold of ecu just to try it out and see if it is tht im starting to get fed up with buying parts to find out its not tht costing me a fortune nah i havent done a diagnostics as the ecu light isnt coming on or anything to throw up any problems Quote Link to post Share on other sites
micky boy Posted April 7, 2011 Share Posted April 7, 2011 Do a diagnostics test first to see whats what the ecu dosnt always throw a light up but it will have the fault code stored if there is a fault... there's a guide on here on how to do your own diagnostics test.
