No Throttle?

[smoggy7]

hi all long time no messages lol makes a change, anyway my problem is when i reverse out of the driveway and i am starting to go up a slight hill i press the throttle and nothing pedal straight to the floor and stalls start again give it a few revs and then it pulls away its a 19. tdi once running its ok on the flat but on slight hills she has a small problem, i also get a small dip or hold-back when putting my foot down only now and again any ideas would be great thanks all smoggy

this sounds like a fueling problem? does it do it all the time or at certain levels of the fuel tank? if the fuel level is low it could be that the pick up in the tank is uncovered briefly and causing a slight hic cup/ lack of fuel just when you call for it?

[smoggy7]

hi thanks for the reply it happens even if i have a full tank of diesel that is what i thought it first was that i havent got enough diesel in the tank but it has happened when it is full i was inclined to think it may be a injector problem maybe not really sure thanks alot any more ideas will be greatfully appreciated

ok on the flat but on slight hills

 

hmm implies maf problems, may be worth disconnecting it and seeing if it makes any difference - costs nothing, if it doesn't get worse then its suspect - I've never heard it causing stalling though - may be worth a try (see faq for location)

 

 

 

ps Helpful to give full car details

hi, its a 1.9 tdi zetec 2001 ford galaxy i may try the maf but surely it would do it all the time if this was the fault not sure on this but my diesel has had this problem for a while now so worth checking it out thanks smoggy

i just found this via the search feature http://www.fordgalaxy.org.uk/ford/index.ph...wtopic=3894&hl= so it seems your not alone with this quirk! have you tried letting the engine run for a while before you pull off? it could be low fuel pressure due to the angle your parked at? allowing a longer warm up period could allow the pressure to build up and stop the problem?

[chromedome]

If it only happens when the engine is cold it could be glow plugs. They are also needed to assist cold running not just to start the engine.

[Guest neil_wiles]

Once again it may be the engine temperature sensor as this will enrichen the fuel mixture until the engine achieves temperature, might be worth a check.

[Guest MATT jr]

could be glow plugs, but could be fuel problem - injectors? some form of sensor may also be at faulty.

 

broken MAF sensor does cause a loss of power through at the range, but it shouldn't cause stalling.

 

whether you have two problems here - i dunno?

hi guys ok here is what happened today when i come to a stop on a small incline and try to pull away i have to give her a real push on the throttle to get her to pick up so anymore ideas on this plz it goes great when picking up no problem climbing on the hills but its again when coming to a stop and then trying to pull away she faults and when putting foot on the pedal nothing there until i rev her a little thanks guys

Does it do this when its hot or cold or both, I think you will need to try and isolate the symptoms a little, it doesnt sound like the maf if it pulls ok going up hill it sounds more and more like a fuelling problem. I have to say though that I would exclude the MAf - it takes 60 sec to disconnect and a quick drive up and down the road (& hill) to confirm its not that - quick and cheap.

 

When you have to give it a bit of throttle - does it stutter or smoothly increase the revs??

[smoggy7]

hi ,it makes no difference when its hot or cold does this on both, when trying to pick up after stopping when i revit a little it then smoothes out then i dont think it stutters any it has stalled on me if i dont give it enough revs it is a strange one this had it on a petrol car years ago but cant remember what it was, thanks smoggy

yep had similiar with dirty carb & needles but hardly likely the same cause here, funny that it does it on an incline - does it matter which way (nose up or down)

[smoggy7]

hi, as far as i can remember just pointing upwards either on a small hill or bigger hill it struggles to pick up until i rev it a bit more than it should we have a specialist herein swansea so i may take it there for his opinion but until i can get some cash together just put up withit for now cheers smoggy

[smoggy7]

hi guys, ok heres the update on this, i disconnected the maf and it hasnt changed the problem, ok today i noticed when on a hill i changed from 2nd to 3rd but had nothing the revs were way up but it seemed to be struggling for speed and my foot was to the floor , so lightly took my foot off the throttle to get it back to a decent speed then by the time i got the top of the hill it went ok then, its like if its missing something but dont know what. so by disconnecting the maf hasnt really made any diff still the same problem either with it in or out so what do you guys think plz thanks smoggy

[NikpV]

did disconnecting the maf change the way it drove at all - if it didn't you have a maf problem - this may not be causing the stalling but its certainly not helping. If you disconnect a maf which is even half doing its job you get overtaken by pedal cycles on slight inclines - it almost happened to me when I was testing the maf. Its such an easy change that if someone near you may 'lend' you their maf if you want to check - where are you, what car have you got 115Ps 110Ps ????

[smoggy7]

hi, i am in swansea and i have a 2001 zetec 1.9 tdi 115 bhp i didnt find any change when the maf was disconnected drove the same as when it was connected, tried on hill put foot down but still the same no go in it what so ever still struggles so not sure wah this is thanks smoggy7

so you definitely have a maf problem then

[smoggy7]

hi, so you are 100% sure its the maf before i go and spend cash and find it maynot be is this the right road to go down first thanks for your help all taken on board but you know with all the sensors and advanced systems these days no wonder we have to pay thriugh the nose cause noone has the tools to repair it lol many thanks smoggy7

[NikpV]

I can't say that this is causing the stalling problem but from your description you have a problem with your maf if disconnecting it makes no difference - your description of driving uphill tallying with everybody elses who has had a maf problem - do a search to convince yourself. I can't believe that it wont help with the stalling problem though

too true - I tried the disconnect test and found that performance was awful - so thought the maf was ok but it kept nagging at me and enough people on the fora said that it may still be a problem so in the end I took the chance ... what a difference it was :lol: :P

ps: you don't need to take the wiper linkage out to change the MAF :D :D :D :D :D :lol: :P :D :D :D

[sepulchrave]

Smoggy, as far as this constellation of Galaxy owners is concerned, if you have a diesel with performance problems...

 

IT'S THE MAF

 

Ok?

 

It is the ONE thing which you can absolutely guarantee will need replacing at some point (usually sooner rather than later) in the cars life. :D
