Just been given a V6 sri vectra that has done 77,000 miles but has a misfire. Not yet had time to look at it but wonder if anyone may have any ideas as to what it may be? I don't intend to spend too much on it and will scrap or break it if it ain't a cheap fix. So any ideas, has any one had a similar problem?
All help and advice muh appriciated
Cheers, Jez

normal- plugs,leads, dis pack..

check the sparkplug wells for oil. if there is oil in there then the cam cover gaskets are leaking because the breathers are blocked.this affects the plugs,then the plug leads,then the dis unit(coil pack).this is the most common cause of misfiring on the v6 engine.if this is the problem it isnt that difficult or expensive to fix.there are maintenance guides on the forum which will be of great help if you want to diy. :y

vectras tend not to leak from cam covers.
last misfire on a v6 veccy, I just changed plugs, leads, and dis. Couldn't be arsed to faff about. No codes on paperclip test, so likely ht.

That was going to be my first line of fire TB. BTW, do those nice alloy cam covers fit the miggy :question

next time you know someone who is giving a 77000 mile vectra away can you tell them to give it to me ,as youve already got one. ;D :y

yes they do, its just you will need to fill the oil up with a long flexi necked funnel

sort of. oil filler in wrong place. Also, because they dont leak, the pressure built up when breathers blocked (main reason Omega ones fail) blows out more vital seals ;)
