hmmm just drove my mv6 round for 3 days with a bust MAF didnt use it much but when i did it cut out alot when you pulled upto juctions and the Overrun was on.
it also idled all over the show but the engine werent shaking!

could it be a Dead DIS Pack?

Where abouts in Shrops are you? if its near Ludlow/Clee Hill i maybe able to take a look for you if you want

Would a leaking exhaust manifold cause a code 73?? :-/

[bighed]

How would I check if leads are all ok? Would a continuality check with a multimeter do the trick?

My mates V6 Vectra Gsi did this not lond after he bought it. He replaced egr valve, air flow meter, coil pack, spark plugs, crank sesnor and leads. Any way of testing these to eliminate them out of the problem?

I'd start by searching for an air leak on the inlet side of the engine, including the vacuum pipes. Any leak here will throw up all sorts of strange codes and give the same symptoms! I had the same problem after I'd had the plenum off... Turned out i'd caught a sealing ring and had a leak under the plenum

It made your car misfire? Would a leak in the exhaust on the top exhaust manifold make it misfire? Cos thet would make engine loose pressure wouldnt it? Thanks for help. Will go searching tomorrow morning

On the odd occasion it would idle it seemed to have a miss... Still think it's sucking in unmetered air! Check the o rings under the plenum if it was removed to do the other jobs

Bit of an update. Just pulled the bottom sparkplug off on bottom drivers side and no change in engine revs and no sparking noise.
Pulled top one off and engine revs dropped, misfired worse and could hear lead sparking. Faulty lead, plug ou coil pack? :-/

[bighed]

Just tried different lead and still no spark? Coil pack maybe?

[bighed]

Coil pack now off n found this. It goes from one side right over to the other  
What could of caused this??




Number 1 is right next to this and thats the one thats not firing.
Wonder why?  
Anyone for a bit of rust??
