Well friends, a gorgeous day today in Southern Ontario and EVERYBODY is out! I have seen everything from a 1919 Model T to a brand to new Lambo (I prefer the T!) to a stunning Herbie the Love Bug. And of course it was the first show/swap meet of the year so there were about 400 LBCs. lots of fun! I also managed to get some parts I needed for the Vauxhall - including - finally a brand new door mirror that matches the holes of the old.
Last you you may recall that I almost made it to this show before I spat out a bolt in the oil pan and prevented rust on the bottom of the car and a decent section of her majesty's highway.
This year I made it there and back under my own steam. That said, there was an issue. As I was coming home - on the highway - so about 60 mph. the car started to jerk/hesitate some. I am deliberately using vague words since I don't want to direct the conversation with my diagnostic musings. It felt more like the car was firing on three cylinders though than (let's say) the clutch slipping. The instruments did not really reflect any different - oil pressure the same, temp likewise - I didn't really seem to have to push the gas harder to keep my speed up and tach was not jumpy. I drove like this for about 3 miles until I came to a convenient exit for me to drive the rest of the way home off the highway - and as soon as I was off the highway, (40 mph) it went away.
This has happened a couple of times before. The first, a few years ago, was another highway trip - and I had to drive that way for about half an hour - It didn't start until I had been driving for over an hour (likewise today it didn't happen on the 45 minute drive out - but on the 45 minute drive back.)
The second time was too and from the Spridget 50th in Wisconsin - where I literally drove hours both way experiencing this.
Any ideas?
BTW 1500 engine running a sing MGB SU (HS4?) electronic ignition (factory) I just refilled the tank with premium gas as I started my journey back (about 1/2 an hour earlier). I have not pulled plugs or anything - and off the top of my head, I do know I have one odd plug wire but, I think that was swapped in after my two previous experience.
