The first thing you have to do is to sort out that misfire on no.1 cylinder.....each cylinder has its own pencil coil, and there's a good chance its that.

Yes and get it done ASAP as you wont be doing your engine or cat and good with a misfire.

thanks 4 the help with the miss fire all done, only thing wrong is the idling problem. tried new map sensor any ideas thanks tim
 
Its usually a fair bet to replace the coolant temperature sensor...the one that provides the engines ECU with information, not the one that works the temperature gauge.

no there aint any warning lights on, some times it runs fine! so very puzzled also with is the coolant temp sensor
 
Usually the CTS is located close to the thermostat housing on the cylinder head, but Kingboy D is the one to advise here.

also been readin up, and some people have been havin problems with the tdc sensor any ideas where this is

Crank sensor is located in the gearbox bellhousing area towards the top. The connections in the plug can be dodgy as well as the sensor!
