My BJ8 suffered a loss of power the other day. Just driving along it backfired a few times the engine became "lumpy" and refused to accelerate but didn't die completely. I stopped and managed to keep the engine running by "blipping", the throttle and it gradualy came back to life and I just drove on with no further problems. I did a further journey the day after with no problems so I don't think it's a carb or timing issue and I've never experienced fuel vapourisation even on the hottest of days.
However, I started it this morning and the same thing happened. The engine dies and runs roughly as though it needs more choke and doesn't pick up. Justs as though it needs to warm up and doesn't pick up when the throttle is pressed. Sounds and feels like it's overchoked or starved of fuel.
So in this order I'm going to check it out tomorrow:-
1 I'll check the fuel filters and look for loose/broken wire connections and plug leads.
2 I'll try and bypass the isolating/imobilising switch in the boot which I understand can be very unreliable. I'm not sure how to do this yet, I never use it. I have a "screw down" battery isolator fitted to the battery terminal that I use for imobilising the car rather than the switch, I'll check that too.
3 It has electronic ignition - I have some points and a condensor but am not sure how to they fit. If anyone has an image of a BJ8 dizzy with the cap off I'd be greatful for a copy.
4 Fuel pump - seems to work ok, the usual fast tick switching ignition on which slows down and stops when the bowls are full. If necessary I'll take the pump off and check it if 1- 3 above doesn't sort it.
5 I'll buy a new coil!
6 New plugs(?) but I think this is getting desperate!
Any more suggestions would be greatfully received.
Thanks
AJ
