TD5 cutting out at high revs

[aew849]

G'day AULROvians,

Have just completed a 2000km round trip in the weekend I noticed the engine was intermittantly cutting out (ie like hitting a governor limit) on the final stretch to home (Grt Eastern Hwy, in the hills between Northam to Perth).

It is a 2004 130 TD5 and had performed faultlessly on the trip until then. Having only had the truck since December, she has covered 8000km's. There was half a tank of fuel, no aircon, air temp was low 30's and was in overtaking lanes in 4th gear 75-80km/h, or 5th gear zooming along uphill 100-110km/h.

Since owning Le Truk, with JC and Tombie2's advice/help I have fitted a snorkel, tidied up the airbox, fitted K+N airfilter, cleaned the MAF, removed the bellow coupling from exhaust and given Stage 1 upgrade to ECU and also fitted BGR 255/85 MT's. Needless to say the abilities of the vehicle is greatly improved :), but this new niggle is annoying.

Having recently looked/fettled the induction, exhaust, and the ecu side of things, the next step is to change out the fuel filter. (There's no history when it was last done, and I hope the service station fuels have been reliable/clean).

Has anyone suffered this glitch and managed to resolve it? :confused:

how high is ''high''? is it under load when it misses and can you get it to do it frequently??
my first thought is over boost?

have you changed the length of the waste gate actuator rod??

cheers phil

Hey,

It's likely got a sticking wastegate, may not have been a problem before as it hadn't had as much boost/ fuel before now:twisted:
Like Phil above has just mentioned, it will then go into overboost and momentarily cut fuel delivery.

Could be the oil in the injector harness, is it still doing it?

I had an issue with the crank position sensor in mine a few years ago, where it lost teh signal at high revs, and it did that but the engine light came on.

For Discowhite/JC/Psimpson7 - sorry no change to wastegate rod. The cutting out was intermittent...not doing it today. Is there a recommended adjustment or modification to the rod, or a thump/whack to free the wastegate up?

The sticking wastegate theory sounds spot on as I have done all the listed improvements in the past 2 weeks, and the weekend soire was the engines first decent run. Admittedly I had to keep pinching myself and flooring it to see how good the engine had come up.

If this is only stage 1, can't wait to see stage 3!!!! Wooooohooooo.

Were you at high RPM & flooring it?

Sounds like a little overboost or sticky wastegate as mentioned by the others...

Sticky is easy - disconnect, spray some lube in the pivot point and move back and forth multiple times then reconnect.

Overboost is easy too - loosen lock nut, lengthen rod on wastegate arm a little (1/2 turns per go)

Yes Le Truk was a low flying vehicle...fortunately I have a licence for that! I have been amazed by the get up and go that the ECU has released.

Thanks for the tip/info on the waste gate. My pommy sourced EGR kit is late so may be on the phone shortly!!
