So I got a quote for a mobile chap and was surprised: $1,600 to $1,800 (without any replacements that might be deemed necessary). I'm sure the convenience and expertise is worth it. But perhaps I just grab a new set for $1,300:

Ford Territory SZ Diesel Fuel Injectors 2.7 V6

Youtube seems to suggest it's a straight forward enough process. I guess I'll still need to cough up for a seat and shaft chamber cleaning kit.

Is anyone aware of any pitfalls I should be aware of?

Thanks.

Definitely go the new injector route. They are not serviceable, and the $1600 test will only tell you that you need new ones anyway for an extra 1300. They can be a right pita to get out, a special injector puller may be needed, or A slide hammer with a home made adapter to hold onto the injector. You will need crush washers and link pipes, they normally come with the injectors if you buy from the uk suppliers. DO NOT remove the seating brackets and bolts from the injector and then try to start the engine to get them out. They will become bullets and can punch through bonnets, shed walls or nearby hoomans. There's a reason they're held in by a bracket and bolt.

Places like united fuel injection or a reputable diesel mechanic may be your best bet, I'd be ordering the injectors myself and paying the specialists mechanic to do the work. Each injector needs to be coded to the ecu so that the thing knows which injector to fire when and for how long. Hope this helps.

No coding required on a 2.7.

Thanks
That's all the encouragement I need.

Are you really sure that's not $1,300 for *one* injector? They're usually around 6 grand a set.

Or about GBP1000 for a set ex UK, that does seem like the price for a single.

Cheers. The Jefferson Ford link says injectors (plural) but has a photo of a single injector. I’ll check before $$!! At 6k a set it that is correct, and a whole new 2.7 engine (again listed on Jefferson Ford page) at 13 k, I reckon the engine seems like a bargain [bigsmile]

I got the IID out this morning for the sake of it. I don’t know how to interpret this but it seems my offsets go out of range somewhere between the 8 to 12% throttle range. Normal or is that a sure sign of sad injectors?

The litres per 100km on the instrument cluster readout indicates about 9.7 l/100km on highway and up to about 13.6 l/100km in start stop traffic. I didn’t take note of the consumption during this log.

Injector offsets are only valid while idling. As soon as you move off idle their values are undefined. Get it up to operating temperature (coolant and oil) before even beginning to look at your injector balances.

Except I think you'll find them out of stock.

Yep - when something sounds too good to be true, it is usually because it is too good to be true. And in this case it was too good to be true by a factor of 6. $1,300 is indeed for 1 injector!

With thi$ in mind, since my offset values at idle seem to be comparable to others I have seen posted I might flip the order on my to do list and do the solenoids etc in the gearbox first.

I'm somewhat convinced that this is actually required, however I do not really know how to diagnose it for sure. The symptoms I have read seem to match the symptoms I'm experiencing. Experience, or lack thereof, being the missing link I guess.

Thanks again for the input. It is very helpful.

Well, it's either going to be the solenoids/seals or the torque converter clutch. Either way unless you are seeing injector out of range messages (< 700 or > 1200 from memory) I'd be looking at the slushbox first.
