The Bougicord magic...I was cynical, now I'm a believer!
Hi all,
After chasing a minor hesitation under heavy load in my 940 LPT for a while, I finally bit the bullet and replaced my pattern distributor cap with a genuine Bosch-made Volvo unit (I already fitted a Bosch rotor a fortnight ago), and put my money down on some proper OEM Bougicord HT leads. I know EVERYONE says that Bougicord is the only thing to use on these cars, but I've always been a little skeptical...owing to a background in electrical engineering, I've always taken the approach of "a lead is a lead, and if it works it works", and used the cheaper Bosch HT leads. Well, I'm prepared to eat my words and swallow my pride. The car is SO MUCH smoother with the Bougicords and the proper cap. Just silky smooth, easily the best I've ever had any of my Redblocks run. It took about 15 mins of running first, but then settled into this glorious smoothness, as if the EZK had calibrated itself perfectly and everything was working as it should. Amazing. I'm so pleased...I wish I'd known this when I had my previous cars, all of which suffered from a little touch of hesitation which I just put down to standard behaviour of a car with the old-fashioned distributor based ignition system. I bet with the proper dizzy and Bougicords, a fair bit of that would have been ameliorated.

I'm still sceptical, two reasons, the first being the same as yours although i am willing to accept better quality leads will perform better than cheap ones as that has been proven over the years. Second reason is the original leads were 30 years old on mine when i changed them from Bougicord to the USA brand name of Intermotor (can't recall the brand at the moment) and all 7 leads turned up plus a new RPM sensor to clip onto #1 lead and plug into the loom from the ECU - all fitted perfectly. They have also performed faultlessly as have a set of Bosch leads on my 827, again from the USA as they're more or less NLA here - had to make the last set myself! Makes me wonder if perhaps the quality in the USA is different to what we get here.

It is the reason why I stick to stocking Bougicord. With running LPG on most of our cars they are the only leads that last any length of time

Had the same thing with my 940 Phil. Partly my fault as I should've changed leads as a matter of course but seeing as the Bosch ones on it looked okay I thought it must be something else.
It was same symptoms as yours with weird hesitation but at strange revs. I was doing a complete overhaul as car had been dry stored for 7 years ( I did also wonder if that might have been part of the problem as well ) and did everything but it was still there. Ordered new Bourgicord leads and that cured it straight away ! The Bosch leads that were on completely disintegrated when I removed them to fit Bourgicords ( they were ok looking when i changed the plugs two months before which was slightly strange ) Interestingly my breaker car which has 231,000 on it has Bourgicord leads on and I'm wondering if they've been on since new. It ran really well before I started breaking as well. Before you ask why I'm breaking it was completely rotten everywhere due to sitting by the seaside for 10 years
