v8 only firing on 7 not 8
gtomo2:
Got a 3.5 efi v8. but its only firing on 7 clys. not played with one before so before i go checking the normal things plug leads, sparkplugs, dissy. is there anything else i should check? its got lpg but mis-fires on both.
Thanks
burgerman:
had a similar rpoblem a little while ago, checked/changed plugs,leads,dizzy cap, checked compressoins, all ok n no difference, to cut a long story shorter, it was no1 injector blocked/knackered, it got changed, and bobs ya uncle, where abouts are you located in this world ?? if ya is in travelling distance(on 7 cylinders) of me (near basingstoke, but not toooo close) i could cast me eye over it?? but most of it should be straight forward enough to check/replace, good luck n keep us posted, if all electrics are ok, when its running, disconnect one injector at a time , and what ever the one that doesnt make any difference is the faulty cylinder
gtomo2:
me a bit far up from you. but thanks for that wil have a look at it tomorrow. hope its something nice a simple can do without the hassle of stripping things off and trying to remember were they came from
bilge rat:
first find which one its missing on, then swap things from another cylinder one at a time see iff the misfire moves to the cylinder you borowed the parts off. certainly a cheap way of doing it . may take longer though. good luck. alan.....

Right played with her today and its still missing check the spark plugs cant see any that are fowled up. but dont have a workshop manuel for her and never worked on a v8 with ingetion before so anymore pointers would be very well recieved. or anyone local to me who is doing nothing tomorrow fancys a trip to swadlincote to come play with it and show me around the engine would be nice
thanks
