Dying/misfire when warmed up

Hi all

First post, so be gentle

I've recently bought an N (96) Disco I 3.9 V8 and am at the end of my tether with regards to getting it running. (It was bought as a "good runner" )

I'm really looking for some advice/recommendation on a Land Rover tech/mech to bring it to as I've exhausted my attempts on what to try in order to get it fixed.

I'm in Rutland; approx. 20 miles from Peterborough/Leicester/Northampton if anyone knows of someone from that neck of the woods who could diagnose/repair a tricky problem.

The problem:

Almost as soon as I got it (1 month ago) I found that, although it starts and runs beautifully from cold, after about 20 miles the car will start to lose power, miss and backfire. Sometimes you can limp the 5 miles or so to get you home. Otherwise, when it eventually dies, it won't start. It cranks and tries to fire but, if it does then run; it'll only cough and splutter for a few seconds before dying again. If I leave it for 2-3 hours to cool down (?) and then try it again, it'll fire up and seem to run fine for a while (not so many miles this time) before dying again. I've usually managed to get home before this happens.

What I've tried so far:

I had a friend (who claims not to be at all mechanically minded) look at it and this is what he has done:

1. Visually checked wiring, distributor, hoses, etc..
2. Replaced ignition coil
3. Replaced ignition amplifier
4. Replaced HT leads
5. Fitted a spider bypass
6. Replaced fuel filter

The problem still remains the same and Rick, apologetically, cannot spare me any more time and has exhausted his "stabs" at fixing it. (I don't feel I can ask him anymore anyway)

Despite these shaky beginnings, I have fallen in love with my Disco and it's already adorned with my pink wipers, pink seat covers, pink steering wheel, etc.. Sorry

I didn't pay much for it, £1000, and wouldn't want to spend a fortune getting it fixed but I'm somewhat stuck with it so would be prepared to pay to get someone to look at it. It should be drive-able to the Northampton/Leicester/Peterborough areas but would need to be hot when it was looked at?

I'd be really grateful if someone could recommend a repairer.

Thanks.

The symptoms you discribe are those of a faulty coolent temp sensor, it's the one positioned just behind the distrubutor.

For an indi land Rover repairer just Google as I did to find one for my part of Kent.
