Hi there. My first post.
I have a 2.5 petrol 90. 1986 vintage.
I've had it about 12 months, whilst it is never going to be an object of desire it was a very good price and is a very sound unmolested truck.
All has been well for most of that time. Runs well and starts first turn of the key and does about 20 mpg.
There have been a couple of occasions where it would suddenly and quite violently misfire. These were normally either when it had been stood for a few moments (such as filling with fuel) when it would still start straight away but miss as you accelerated away, or if you had been going on a steady throttle for a while and then accelerated. I'd put it down to some form of fuel vaporisation and was going to reroute the fuel lines further away from the engine.
However, in last few weeks problem has got much worse. It will stutter even when cold, sometime when running along at a steady speed. But it does not happen all the time. the other day I did a 3 way trip, 1st leg coughed and spluttered most of way (10 miles), same for 2nd leg, then on last leg again 10 miles ran without a hiccup.
Certain it is a fuel issue rather than ignition, as dizzy, points, coil, plugs and leads were all new when I got it and are correctly set up.
Had a look on the posts here, but nothing sounds quite like what I'm experiencing.
Any ideas? thanks.
