What are the readings i would expect on the Voltmeter? Andy

Thanks for the advice. Car is a V reg 2.8 Manual GhiaX and has done 75000. I had the plugs and leads changed about twelve months ago before we decided the coil pack needed changing. Fuel consumption is somewhere between 10-15 mpg. What/where are the sensors you mentioned. Especially the temperature sensor. I did think it may be something to do with the temp - during the winter it work okay, now its starting to warm up, its misfiring again, and occasionally stalling when I slow at junctions. Would connecting a diagnostic to it tell me the problem? Thanks

I wonder if anyone could help with my Misfire problem! I have a 99 V6 GhiaX. It normally runs fine - thirsty - but fine. lately i have been experiencing an intermittent fault where it misfires badly, no power, sounds awful and fuel consumption goes through the roof. I first had this problem about 10 months ago, my local garage said it was a faulty Coil Pack. We replaced this but to no avail. after several weeks of tinkering and swapping coilpacks (back to the original) the problem went away, and i had no problems over the winter. But now the problem has returned, its not all the time - but most of it. Any ideas would be very helpful. Thanks
