hello
i have a 2000 4.6 vogue that has just started to miss fire - sounds like it is running on 6/7 cylinders all the time
it has produced the following fault codes
2 lamda sensors
cam sensor
low fuel pressure

can any one please advise which sensor is more likely to cure the fault or is it a case that i will have to change all 3 and then get a re-diagnostic check
also the cheapest place to buy the sensors and is it worth risking 2nd hand

thanx for all ya help...

don't buy second hand, you don't know what your getting. You can check the lambda sensors with a multimeter. Find the black wire that goes to each sensor and attach an extension to it that will reach into the car. Use the multimeter to test the output of each one in turn. You can use the fag lighter socket surround for an earth. At idle with no load you should see the Reading going from 0v upto .8v every second and back again. Under heavy acceleration they should stay at .8 and on the overrun go to 0v

hi
thanx for that
if the diagnostic says the lambas are faulty surely checking them is not necessary or is it...
would these cause the car to run as it does or is it more than likely to be the cam sensor - any way of checking this - also where is it positioned

kind regards

faults get logged for all kinds of reasons, not neccesarily broke Sensors. In reality it is more than likely to be the ht leads.a missfire may well give you a rich lambda fault. Check these at the dead of night in a realy dark place, look for blue arks from the leads and at the top of the engine at the back where the coil packs are. They may only be tiny flashes. If you have standard leads, it's worth replacing them with good quality ones as the originals are very poor anyway. The. Cam sensor is at the front of the engine, not sure how to test the output from that though.
