cheers guys i have just been outside with my torch 11pm here !!!and yes there is another sensor i didnt realise was even there , tommorrow i will take the alternator off etc and check it out , it looks damnb awarward to get to , i havent got the other one i ordered yet as the company has them on stock but ran out , if im quick i could cancel it and order the other one ,,, cheers julian

 

quick update , alternator and power steering pump removed got the coolant sensor out did a resitance test cold all within in spec , however put it in a pan of boiling water resistance went down to 5.2ohms x1000 . there fore i guess its below working tolerance new one ordered could this be the cause of my missfire , let you know when new one fitted , regards julian

 

In boiling water the reading should be around 1.0 x1000 or 1K ohms. Your reading is 4.2K higher than that. So as long as you feel you did the test correctly, then the CTS is definitely not going to as low of a resistance as it should.

 

Engine miss is common problem BEFORE doing anything you should always perform this bulletin.
