Intermittant loss of throttle response Puma 2.4

[Brid]

Last week, my 2.4 Puma suddenly lost throttle response in peak hour traffic...

It was driving well, going through the gears from traffic lights. 1st & 2nd as normal, then 3rd gear and backed off with the traffic flow. Reapplying the accelerator and ZERO response. Tickled it several times, and power again. This was the same pattern until I reached my destination. Which ever gear I eased up in, and reapplied the throttle it would go dead.

There was no engine malfunction light, and when I restarted the engine to head home again after 15 minute stop, all was well. Back to normal again. I had thought it might be the potentiometer (?) thing connected to the accelerator pedal. Definitely not the fuel filter, or tank breather.

Anyone else had this happen to throw any light on things?

Happened a few times in my wife's Astra. Suspected accelerator pot. Problem disappeared and hasn't come back. Jim

I had a similiar prob with the throttle potentiometer on a Td5 and it left us stranded in Newman some years ago.
Vehicle would tick over all day but putting power on made it do some things like bunny hops or the engine would cut out.
Then it took nearly 3 weeks for it to get trucked back to Perth as the truckies didn't want to unload just to get our vehicle and camper on to their truck.
Best get it checked out as you could be left stranded as even in a town as big as Newman absolutely no one could or would even look at a Landie.

I booked it in to MR Automotive a few weeks ago (before all this happened) to get a thorough check over, and I actually dropped it in there this morning, so it's in good hands.

The problem is that they'll need it to play up on them to identify where the problem is. Otherwise, there's likely to be an element of guesswork. The problem happened once again this morning, but only on one occasion. It'd be a bit of good luck if it happened when MR test drove it.

Is there a Ford Dealer in Newman?

Same engine as the Ford Ranger and Ford Transit van?

The vehicle stranded in Newman was a TD5.

I've had the throttle ignore me in two different situations in my PUMA. The conditions aren't quite the same as yours but it might be worth thinking about:

1.) Throttle response went to about 75% one day. turned out to be a FILTHY air filter. That said, the throttle still worked, power was simply reduced very consistently across the range.

2.) Radiator got blocked up with mud and so occasionally when it would overheat, especially when accelerating in traffic or on the freeway up a hill, the engine would simply ignore any right foot input. Once it had cooled down (a few seconds only), it'd be back to normal. have you been through nay mud? Carrying a heavy load?

Keen to hear what your issue is and whether it's related or not.

i've been having this problem for ages actually. and same thing happened to me this morning.. thankfully i was a street away from my office and managed to limp in..

went for a drive again 3 hours later and alls well. same as last time..

haven't tried anything yet.. ain't too keen on changing fuel filter myself, priming it again seems awfully troublesome.. might check the air filter later.. everything else i'll have to bring it into a workshop..

do let us know if you find anything..

According to this videao, "Priming the filter (which seems to be just filling it with diesel) prevents you having to bleed air from the fuel line."

Fuel filter change begins at 7m21s

Would the PUMa store codes for overheating, and perhaps throttle pot failure? I would have thought the dealer could locate those codes?
