Hi guys, I have Just got into my mig after about half an hour of being away from it and its now shaking heavily on tickover and sounds like its misfiring under revs. Any ideas? Sparkplugs have not long been done. Could it be a faulty lead?
Just noticed my avatar has gone funny.. Was ok yesterday. (normal size) Any ideas :-[ :-?

I personally would check the leads for soundness (has it been in heavy rain today?), but many on here will say straight away "crank sensor" which when it suddenly goes causes the symptons you describe. :y
Have you done a paperclip test? I ask that not knowing the model you have which may rule that out in that manner. Please place your vehicle details into the profile:)
-
My apologies. Its a 99 2.5 V6 CDX. Not done paperclip test as no eml light has come on. Will go do it now.
-
AA man has just been and says try some new ignition leads, but could be coil pack. Anyway of testing this as new leads from vaux aint cheap
Also will there be a fault code if no eml light has come on?
:-/

Not every code causes the light to come on.

Just tested and its given me code 73. Mass air flow sensor voltage low???? :-/
-
Will it still be ok to drive on short trips as got to take mrs n little un to see midwife tomorrow afternoon.
Hospital is about 3 miles away

Most likely an air leak then.

Wouldn't keep using it for too long without resolving it
-
Unplugged mass air (if it was the right one I unplugged) and the engine almost died then picked up but revs sounded lower. Air leak?? would a blow in the exhaust do this? Just pulled a sparkplug out and it runs exactly the same?? :-/
-
As above, exhaust blows (sounds tappy on start up) would this effect it in any way? :-/
-
Wouldn't have thought a blowing exhaust would have caused your problem.
Check for air leaks like already suggested :y

Could do, depending on how bad, and where.
-
It sounds like just behind and down from top plenum area. Would that be manifold? Bet thats a right pain in backside to change??
-
Would exhaust blowing bring up code 73???
-
Really need help on this as somehow got to get to the hospital tomorrow :-[ :-/
-
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
-
tmx u have pm :y :y :y
-
Would a leaking exhaust manifold cause a code 73?? :-/
-
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 :y

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 :y :y

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? :-/
-
Just tried different lead and still no spark? Coil pack maybe?
-
Coil pack now off n found this. It goes from one side right over to the other :o
What could of caused this??

Behind the driver's side of the V ie next to where you've just removed the DIS! ;)
