My RP does exactly the same! Usually climbing hard in 3rd gear and just a single miss. At first I thought that it was due to the worn state of the distributor, so I bought a newly refurbished instrument on Ebay. Fitting it made a vast improvement to the general running of the car, but made not the slightest difference to the single miss when climbing. As the car was running on what looked like the original coil, I thought that might be the culprit, so I changed it for a new Remax. That made not the blindest difference, so I fitted the old coil back, as it looked the part and appeared to be good. I have changed the the coil and distributor leads since, with good quality copper cored wire and new crimped tags at the plug ends. That has made a difference. The car will still do an occasional single misfire, especially if the engine is really hot, but it doesn't happen nearly so often as it did, almost to the point of rarity, in fact.
I don't suggest for one minute that changing the plug leads is a cure. After all, my car has been serviced and tuned several times over the past four years of ownership (The distributor, in particular, tends to 'drift' a touch, so the timing is checked and reset every 2500 miles), so any of my sundry ministrations could have had an effect. or none! However, the new plug leads seem to have reduced the occurrence to nothing more than the slightest of annoyances.
Yes I would like the problem to go away completely, but have come to accept it as part of the character of the car.
