98R maverick 2.7td man stalling

[laidlaw]

drives along starts fine, however it sometimes stalls when you pull up at junctions etc. help please

Ok, we going to need a bit more than this to go on.

Does the engine surge when ideling. What is it running on Diesel or Veg oil?

Start cheap and work your way up. Air/fuel filter, check its clean. MAF again check its clean.

Does it have the hand throttle? Mine idles a bit slow, but a notch on the hand throttle and all is sweet, could be worth a try to keep the revs nearer 750 at idle.

If you put your location a bit more precise you may have members close enough to give a hand. David.

98R I'm guessing it's a tdi not td sounds like what Clive had which I think it was the cranksensor but check codes 1st even if the mil light is not on as the ecu self checks so failing cranksensor might be a code but we do really need more info about problem and car so we're not guessing:thumbs

I have exactly the same problem in my Terrano. Mine is a 1997 2.7TDi. It starts up fine and runs ok. However it will sometimes stall when I am pulling out (forward or reverse) of a dead stop situation. I also noticed that its idle is a bit rough especially when cold but I don't know whether this is normal on Terranos as I have only had this car for a month or so. My mechanic told me there is nothing wrong in my car and he told me that it is only stalling as I need to get used to giving it more revs (as in around 1750revs) before taking off unlike my previous 4x4 which he told me had a much bigger flywheel and had 5 cyclinders hence being more torquey. However, I am still not convinced that it is just a matter of me needing to get used to it and not that the car actually has something wrong and since I've never driven another Terrano I cannot compare it. Incidentally I run the car on normal diesel but have no idea what the previous owner ran it on.
After browsing through some posts on this and other forums, I cleaned the MAF but this didn't solve the problem. Also looked for the infamous banjo fuel filter but it turns out my car doesn't have one. After running out of ideas, this morning I took the car to a garage which services injectors and diesel pumps, and they told me that the the number 1 injector is a common fault on this car. They checked my no. 1 injector (resistance I think?) and they told me its clear that this injector is faulty in my car. They told me I need to replace this faulty no. 1 injector with a new one, and offered me an appt next week to get this done. I also thought that whilst the car would be there, I should ask them to remove,clean and fit back in the other 3 injectors especially as my Terrano has 129,000miles.
Do you think this could be the solution to this problem?

One thing I should have added is that in some instances after stalling, the ECU gave the following error code: 1 8 - Fuel quantity adjuster / position sensor malfunction

 

[jims-terrano]

Both Myself and Clivvy had similar problem which got progressivly worse. CKP Sensor (Crankshaft Position Sensor).

Is it TD or TDi engine, TDI has an intercooler on top of the engine and has more electronics. It's the TDi that has the CKP Sensor.

Now you are a full member checkout the downloads section in Quick Links at the right hand side of the yellow bar at top of the screen. There are loads of how to sheets and one of them is how to read fault codes on the tdi with nothing more complex than a paper clip:thumb2

 

[clivvy]

id be 99% its the CKP. I bet from cold, its probably alright? then, when warmed up, it randomly stalls?

£190 ish will get you a nice new sensor and you wont have to worry about it agian. Buy a used one, and you will potentially get the same issue as these are just magnets and magnets like those dont last forever...id buy new if you intend to keep the car a while.

Clivvy, don't forget the 2 or 3 wire versions:doh

My car only stalls when taking off from a dead stop. So far it has never stalled when slowing down to a stop. Is this symptomatic of a faulty crank position sensor or would the symptoms be different if this sensor was faulty?

yup, still a symptom. try to note if its any better from cold. You should probably read your codes after the stall, this would point you in the right direction - does the MIL light come on when it stalls?

 

[mariner]

The engine has stalled both when cold as well as warm.The MIL light doesn't always come on when it stalls. The few times it did it gave error code 18. I'm not quite sure what this code means.

Thats the code i had with the same symptoms with my 02. ended up with new diesel pump.the previous owner ran it on used veg oil engine oil which i didnt know till pump was removed.the rotary was all cacked up so when throttle let off wasnt distributing fuel correctly.if i sat stationary and revved to 4k let foot off as it came down it stalled.

I tried this on my car, i.e. revving it to 4k when stationary and letting foot go, but it won't stall.

I have also just realised that the fact that the guys at the repair garage got no resistance off my no. 1 injector does not necessarily mean that this is bad, as there are 2 types of injectors, with the Bosch giving a resistance reading but the Zexel do not. I am not sure what brand my injectors are but I do know that my MAF is Hitachi which seems to be an indication that my car has Zexel fuel system after all. I'll tell them about this before they attempt to replace this injector with the Bosch ones they have instore

 

[mariner]

The mechanic confirmed that my injectors are Zexel. I have kept an eye out to see whether the stalling of the car happens more when its cold or watm, but there's no difference really. the guys at the garage told me it could be some electrical component within the pump (electrical governor?). Is there any way in which I can confirm whether this is the problem or whether it could be something else like the Crank Position sensor, No. 1 lift sensor, etc?

I already suggested the CKP, could easily be that. Only thing you can do is check it electrically and ensure the correct ohms are presetn, but i dont know how to do that. Same with the Number 1 injector.

£190 sounds a bit steep i didnt pay any thing like that


Will look for the link

Hi I have the same Hitachi controlled terrano, I suspect its just the way you are driving, the engine has little power low down the revs and needs a heavy right foot and a slow lifting left foot to stop it stalling.

regards bri

 

[mariner]

I have had the injectors inspected. The guys at the garage found them to be ok and gave them a quick clean and back in. No difference in my car's performance since except for a somewhat smoother idling.

@Wildbri My mechanic's point of view is exactly like yours - i.e. that there's nothing wrong in my car and that I just need to get used to applying more right foot and releasing clutch more slowly. But I still have my strong doubts, as if this is the case, then the Terranos must be very very very prone to stalling - mine is almost certain to stall if I'm stationary in any upward incline (uphill) and want to start moving, unless I apply handbrake and rev car significantly beforehand before I release clutch if you know what I mean (the sort of thing you usually have to do with other cars in really steep hills only).

@Clivvy as regards your suggestion re CKP sensor, yep this could be the case, but the fact that it happens equally when cold as well as when warm, and the fact that I only have problems when taking off from a deadstop is making me have my doubts on this.

I don't know whether if it is of any relevance but I noticed that if I leave the car to coast downhill from a deadstop on neutral, as the car starts moving, the rev counter will first go up, then stumble down, then go up again. I am starting to doubt whether this is related to my car's speedometer as my speedometer is wavy (it vibrates a bit especially at lower speeds). I also know that the Terrano's electronic fuel quantity adjuster uses vehicle speed as one of its inputs (infact our car's idling speed is low at around 750rpm when the car is stationary and higher at around 1000rpm when the car is moving). Could this wavy speedometer be the root of my problem? Is there any way I can check this and what parts would need replacement to sort this vibrating speedometer issue?
