Having some problems with my Ford Sierra. After driving it for a while, the engine starts missing and I have to pull over and switch the engine off. It will sometimes start back up straight away and carry on for a couple miles before doing the same. The longer the car is left to cool down though, the longer it will run before starting to miss again.
It first started on a 100 mile journey after about 95 miles but I then took it to a garage and had the tappets repaired, distributor checked and rotor arm checked. I thought it was ok then and drove it over 120 miles with no problems but then it started again. Ever since then, it has gotten worse and happens within the first 30 miles.
Spark plug leads, spark plugs and distributor cap have all been changed, which I heard are common causes for this problem on the Sierra, but hasn't solved the problem.
Any other ideas what could be causing this?
Engine is a 1.8 CVH

Head of the engine was rebuilt about 12,000 miles ago so I'm doubting anything mechanical with the engine itself but ignition coil and crank sensor are two things that have been suggested to me before. Just trying to get it right in one shot this time because I've already spent enough money on this car and it's on the verge of either being scrapped or sold for spares or repair.

For a start if it was the crank sensor it would brake down and it would not start till the sensor is changed to me is the ignition coil,to test the coil turn the key on but do not start the car live ignition light on for about 7to10 min if coil get hot change coil if not change your ignition module.

Dear If I am not wrong your cars piston rings worn out,After getting temp at engine . Engine oil up to the top of piston,and that oil make poor fuel burning that make missing .

Yes, Mr know all has hit the nail on the head.
If you know where it is ( ign. module ) Run the car and when it starts to play up pour cold water on the module to test it .
But I think you will have to have it changed anyway.
Good luck.

i believe it may be your coil, these heat up as they produce a massive voltage, and the windings inside can fry, just a guess!
