XF Carby Stalling.. - Ford Forums

Hey Guys..

last nite the XF stalled on me twice at the lights...i had driven for a hour or so and parked the car. Came back after about 5 hours, started heading home, after about 1/2 hour of driving it stalled after i had stopped at a set of lights. Restarted it, but it stalled again straight away. Restarted again but kept foot on accelerator, and managed to shift back into drive, got moving again. All was okay until another 20-30 minutes later it did the same thing.

It also felt very underpowered when driving it yesterday, like some sort of major flat spot has developed...

Any clues?? i dont want to risk it stalling in traffic and not restarting again..

Thanks

Mum had problem on her XF recently....

Was blocked jets. Turned the idle screw up all the way to keep it idling.

Have a look down the throat, and closest to the front of the engine, there is a jet. Should be spraying fuel in. Whereas mine the fuel was trickling in.

Carby needed a good clean and rebuild, problem solved.

It could be a number of other things, but our mechanic has seen heaps do this, just the jets getting gummed up with dirt and crap.

Funny thing was, it just happened all of a sudden, no real warning.

i had a bluebird that did almost the same thing you would drive then start playing up you turn the engine offf then on and its fine ,but underpwered ,and it would stall every time you get at the lights .with every thing that woulld happen i thought that it was thae carby .blocked .nope ..[though giving her a clean helped ] try these replace the fuel filter give carby a blow out [clean]

check to see if there is a air leak at bootom of carby
air leak at maifold
vacum hose leaks any where

if its none of these then try replacing ya points

thats what it ended up being on the bluebird .even though it seemd like a carby prob

check the vacum hoses if the car stalls after getting a little warm

also make sure you are getting good spark and fuel .

let me know if its any of these

another thing it could be is check if there is a vacumm line going into the auto and if there is a leak there .some cars apparently have a vacum line into the auto and if you are having troubles getting the thing off the line it may be worth checking [im not sure if the xf's do ,i could check but its too late and wont be able to see anything .

anyway there are a few things that you could check on

4.1's have an electrical solenoid that runs the idle circuit. It may be faulty. They are also known for distributors to fail when hot and come good when cooled down. Usually due to worn bushes causing the reluctor unit to pole out.

I think ours has a similar problem, but it's an EFI.

After driving for about 5 mins, the power will either drop off suddenly and come back, or drop off for a while then come back. Kinda like there's something stopping the engine, but not cutting it out completely, just the revs dropping. It will also stall sometimes when you're idling or going very slowly - not good in traffic.

Dad's the car wizzard so I'll get him to look through these replies to see if there's anything he hasn't tried.

Thanks for the help so far guys..

i dont think its the distributor..as i can start the car up again straight away after it stalls...usually it has cool down for about 20-30 mins to restart if it is the dizzy..

id say its probably the carby, as its last rebuild was in 2000...so its probably due for another one..

although my throttle cable has been jamming a bit in the mornings..could that have any baring on the stalling??

Most likely carby, but I'd also suggest you make sure your plug leads aren't leaking: this can have a similar effect.

Well on further inspection this morning i found that the spade plug coming off the idle solenoid had snapped off, and the previous owner or a mechanic had soldered the broken plug back onto the solenoid.

A few jiggles of the power wire to the solenoid and the whole spade plug came off, so i assume that its been having a bad connection all this time..and may attribute to my rough idle that this car has had since ive got it...why wasnt it replaced!! i coulda been stranded!!

that feels better now..:-)

Anybody know how much these solenoids cost?? and where i can obtain one??

Thanks

Can always try Ford (they are not that bad all the time), a wreckers or a carbie specialist.
