Grahamgl Posted August 6, 2008 Report Share Posted August 6, 2008 Hi, I have just been out for a spin in the car and it has started to occaisionally mis-fire or just miss and causes the car to slightly judder. It is particularly noticable at lower revs. I have cleaned out the float bowls and the missing is still occuring. From my limited knowledge I would think that this problem is being caused by an electrical fault. Before I go ahead and replace plugs, points, condenser, coil and leads can anyone suggest the most likely cuplrit. When I bought the car last February I replaced all these items with new bits including the low tension wire inside the distributor. Any advice on my starting point would be appreciated.

Ade-TR4 Posted August 6, 2008 Report Share Posted August 6, 2008 Hi I'd start with the rotor arm - repro ones don't seem to last 5 minutes. If no improvement, just make one change at a time! Cheers Adey Quote Link to post Share on other sites
88V8 Posted August 6, 2008 Report Share Posted August 6, 2008 My 6 was misfiring today at low speed - some kind chaps at Croxley Green diagnosed plugs fouled and after a clean, all was well. Now why they were fouled still has to be determined.... Ivor Quote Link to post Share on other sites

88V8 Posted August 7, 2008 Report Share Posted August 7, 2008 Ivor could be Choke lever not quite returning fully. Thanks I'll look at that. I noticed whilst not polishing the tailpipes that one is brownish and one is blackish so it is running rich or not fully burning, by the time it gets to the tailpipe hard to know the difference. I could put the Gastester up the pipe but that will just tell me there's a lot of CO in the exhaust. I changed the plugs a while ago to BP7ES, perhaps they're not hot enough. And perhaps now I'm giving it a bit more wellie - altho not on this particular journey due to traffic - there's more oil recirculating via the breather, just enough to overwhelm the cooler plugs. They did look quite wet, altho that could have been petrol. I was reading with interest Stan's exposition on catch tanks - something I don't usually favour - in response to Robin's thread. To be continued - oops mustn't hijack this thread. Ivor Quote Link to post Share on other sites
