wild foamy Posted April 29, 2011 Share Posted April 29, 2011 Hey peeps, The XJ finally died on me last night, coming back from newbury along the A4 with a chinese takeaway in the tankbag, just about got into hungerford when the power died and it would not idle, sounded like it was struggling to run, possibly starved of fuel?, it died when pulling away from a roundabout, after i had pushed it round the corner to a petrol station and swore at it a bit it started and began to run correctly. Im going to do a plug chop on it today and see how that goes, its running a motad 4-into-1 with more holes in it than a sieve, thats the only engine mod on it as far as im aware so, why has this happened, what has caused this to happen and how can i prevent it happening again?

barkwindjammer Posted April 29, 2011 Share Posted April 29, 2011 Yep Foamy sounds like a momentary fuel interruption, is it running ok now ? Link to comment Share on other sites More sharing options...
wild foamy Posted April 29, 2011 Author Share Posted April 29, 2011 Runs okay now, thing is at high speeds if i open the throttle fully it hesitates before powering up fully, just looked at the plugs now and they are chocolatey brown colour, where should i be looking next?

barkwindjammer Posted April 29, 2011 Share Posted April 29, 2011 Mines hesitates too-its called lag, plugs sound fine with that colour, it might just have been a vac in the tank, check your tank breather tube, if it happens again open the filler cap and you might hear air rushing in ?

wild foamy Posted April 30, 2011 Author Share Posted April 30, 2011 Just had a thought, are there any filters or anything on the top of the fuel tap inside the tank? Link to comment Share on other sites More sharing options...
