Engine misfire
Discussion
Morning..bit cloudy and light rain forecast for this morning here, but a bit of sun later for a drive I hope. Who's on the road today?
I've been able to get the old girl on a good run a couple of times recently though and blown out the cobwebs a bit but she has now developed a major lurching misfire particularly with sharper acceleration once 90 degrees has hit. Not immediately after 90 but 5-10 mins or so later, ok before this. I dropped into Burtons and bought a new dizzy cap, rotor and leads which I swapped over the other evening and am going to change the fuel filter which hasn't been changed for a bit....I put some redex cleaner in and wonder if its worked a bit of c*** through. This might all solve the problem but wondered if anyone else has had the same issue?
Oh and while I was changing the leads I noticed that Lead positions were opposite to desribed in the Haynes capri and Steve Heath bible, i.e when looking at the distributor and vacuum unit position as being correct its currently 5-1, 6-2, 4-3, 3-4, 1-5 & 2-6 like its 180 degrees out. Always been like this since I've had it, thinking I should maybe look into it and check the timing while I'm at it?

Cheers for the ideas Fellas,
I've not actually managed to take it out yet since working on it, but while I was changing the fuel filter I noticed coolant leaking from the water pump and consequently a low level so I reckon that was the issue or at least that and a combination of the other items I changed. New pump now I guess.
I'm in the middle of changing the rear hood section at the minute, just need to glue to the top hoop and trim, I already did the targa's a few weeks back, although I think I paid too much for the material and hood section. Then again I think I paid too much for thd car bearing in mind what they are selling for and the condition I bought mine in, I actually looked at one close to me but turned it down as it had no MOT and it was the first I saw ( a much much better buy in hindsight)....then I went and bought mine because I travelled miles to see it and felt compelled to....never a good idea especially when I knew bugger all about the S in reality...still its getting there even if I'm having to renew just about everything in sight...and out to be fair.
