I don't have the answer to your question but when a car is at a "certain age" you have to decide how much money you're going to throw at it.

it's a toughie.. it's not an old car, but it's old enough to cost some money to keep it on the road.... a false economy, maybe?

i agree totally, but its just so annoying to think it could be something so trivial, thats probably staring me in the face, there are no other faults with the car what soever, thats why i don"t really want to get rid of it, cars can be a real pain sometimes can"t they? many thanks for comments anyway.
Lift up the bonnet and spray WD40 in a willy nilly fashion. Works for me :-)

i think theres alot more to it than that.
-- answer removed --
has it been on a tech2 or similiar diagnostic system ?
As said a diagnostic check should have been done before you spent the money on the service, was the right HT leads replaced? Plugs? Filter etc, have you had a new cam belt fitted? if so was it timed right? It may have slipped a tooth, Something tells me you have a carb problem! are you yourself capable of stripping and replacing the carb?

i assumed the garage had done everything they could to solve the problem, twr, unfortunately i know nothing about mechanics, i would"nt have a clue where to start, when you say carb, do you mean fuel problem, someone i work with suggested poss fuel pump, many thanks for your comments.
Hi as Chas said, your best bet would likely to be a tech 2 machine, which will give you a print out of how the whole system is working. I had a Saab v6 recently which actually is essentially the same engine ( they use a vauxhall block) and there were a number of things at fault when I tech 2'd it, and none of them were cheap, however a tech 2 test should cost you about �40 so you know where you're going from there, as ' poking and hoping' on such a complex engine will only frustrate you and cost you a fortune on things ' it might be'.
check your cambelt timing, longshot I know...
Question Author
i think i will do as you say obnoxious, many thanks.
Question Author
many many thanks for all your comments, i guess its a long shot whatever i do, its just so bloody annoying, spending the money, but never getting the problem solved.
twr there is no carb on a 2.5 litre vauxhall vectra they are fuel injected.
please please possibly suggest anything that could be causing this problem

.........................................................

look at the first line in your original post ,you will find the answer there!
tonyav unfortunately theres a lot of folk on this website who know ***** all about cars but guess anyway to make everybody else think that they do!! anyone whos ever worked in the motor trade would know that carburettors more or less havent been fitted to cars since 1992/1993 when good old Maggie stipulated that cars had to have catalytic convertors therefore most cars had to be fuel injected to meet the emissions criteria for that time.
Oh my god, we all make mistakes " Dont We"!!!!!!
Oh my god, we all make mistakes " Dont We"!!!!!! Sorry Chedd I should have said Fuel Injection Please Please forgive me, I will not do it again Jesus Christ.
Question Author
not to worry twr, i know its not a carb, and that it obviously is fuel injected, anyway as luck has it apparently, today after it was looked at again, it all points to fuel injecters, so hopefully i will know on wednesday, after the work has been done. thanks anyway.
Hi Chedd, Well some folk get excited when we make mistakes!! you know what I mean, Regards the Injectors they are not a big job to do & you can get refurbished Injectors they take yours in part x then do the same again, going off the year of your car that is no big deal regards mileage providing the belts, filters, Fuel filters are changed on a regular basis it should do the clock twice, It is cheaper doing that than replacing the car, at least you know the car & it's history good luck with it, & Again very very very very sorry LOL Trebor.
Question Author
thanks twr, yes i know my car and i really don"t want to part with it, unless i really have to,i"ll let you know on wednesday eve if that is the problem, if thats ok. thanks again.
