mixture problem

[mixin]

Ive had my saxo 1.6 vtr 98 put on a diagnostics system and its coming back with mixture control fault, Any ideas what this could be?

it could be fucked

rite ok??? so you no idea then?

lambda sensor, fuel pressure regulator, injectors, number of things it could be. the garage should have gone into more detail and told you whats wrong. just knowing the mix is out doesnt really help

[mixin]

Thas what i thought that they should of told me more. So it would be worth me going back then, If it helps shed any light im also getting hesitation with it, almost as if its running out of fuel but its not?

[LeeM]

id go back to the garage and find out more, hesitation will be down to the fuelling problem

They hopefully should be able to tell you what fault codes are showing, even if they dont know what they mean. Then armed with the codes you can find out the problem.

[mixin]

[phunkymonkey]

[mixin]
