Intermittent power loss VTS

[DansexysaxoVTS]

hi i have Intermittent power loss on my VTS iv have code read it and the is no codes it can be fine then it just splutters and loses power so i pull over and the wait for a few mins then its all fine

I replaced the coil pack but it made no difference

Had a full service 3 weaks ago

Any one got any more ideas thanks Dan

next time it does it --does the rev counter drop to zero even when car is still ingear --if so its a power supply problem probably on the main feeds to ignition switch

No mate the revs drop but only to like 1500 then it dont want to pick up and splutters and boggs right down

[Wee_monkey1987]

cheap method is cotted wall pud bit of WD40 on it and clean the map sensor out mine came out black covered with oil

When you say you had the code read, was it just a basic code reader?

As that would only show up if EML is on.

I have a Lexia which shows up prending code and temp faults, so a lot more detail

Thanks mate will order a new green temp sensor and have a look at the intake temp sensor will be back later to let you know

[DansexysaxoVTS]

Fitted a new green temp sensor and another fuel filter this afternoon but car died on the way home from work lost all power had to pull over and let it idle for a few minutes then it was fine

the car idle fine not lumpy or any thing

Does it run rich?

[DansexysaxoVTS]

Does it run rich?

no mate is had a new lamda last month for mot was fine on emmisions

[vtr91]

it might be worth plugging into a machine and reading some actual values and comparing them to what they should be.
might also be worth checking the quantity comparison for the fuel injectors.
use something like the bosch kts

[DansexysaxoVTS]

took it for a drive last night scanned it agine this morning and it came up with code

291 adaptation mixture control

Can any one shred any light on what this means thanks

[saxova]

google search showed 4+ replys pointing it towards a injector :

P1291 Injector High side short to GND or VBATT - Bank 1

So check injector wiring / check for leaks / send them off to be cleaned :y:

[DansexysaxoVTS]

Yeah mate just goggled it as well will have to have a look at the injectors thanks

[vtr91]

unbolt the injector rail, pull the injectors out (all attatched still), lay some cardboard underneath it,
get someone to crank the engine over for you and see if any of the injectors have a dodgy spray pattern :)

[DansexysaxoVTS]

Hi i sent my injectors of to be recondition got them back yesterday and fitted them but the car is still the same and came up with 291 Adaptation mixture control agine

Any one got any more ideas im thinking

disconect the lamda sensor and see what it is like but it is only a month old ?

Fuel pressure regulator ?

And a compression test ?

Any ideas will help

[Wee_monkey1987]

[DansexysaxoVTS]
