Thread: A mate's TD5 woes

yes there is a lot of experience and knowledge here on this site. im glkad i came to take a look so thanks frontier. hopefull one day soon driving this car will be the pleasure it should be. and thanks verymuch for everyones help with this, i will do the checks on the things mentioned at lunchtime tommorow.. the ground wire will be easy for me!
ill check for the soot and the bubbling when i have a look at it tommorow- and sus out exactly what the terms mean!!! thanks very much for the big pm list BLK knight. i was real happy to see somewhere to begin looking.
it was sure enlightening and ill take another look at that now that i understand things a bit better. i can likley now exclude a few things now we have better idea of exactly whats been fixed and whats happening.

i did take it for a five hour drive with no problem at all today.

but it did hiccup on the drive home after they changed the accellerator pot doobie on friday. i will be getting onto the dealer to ask why i had to pay for parts and service under my warranty period too.
next time i would rather go to the other guys suggested here if they arent gonna honour a warranty. some guys there are really good and others not so. i like talking to a mechanic really.

i can see no oil around the looms. i had a decent peel and look the other arvo. when the loom went oily that time it repeatedly hiccupped a lot.
i have since remembered that the mechanic did say he found oil in the loom and so he never just changed it for fun.

since they changed that the hiccups have been comparably very short lived, actually remiding me of the time it first occured the weeks before the loom went bad.
i would ring the guy that did own the car originally to see what he knows but i dont want to bother him really.

i still have a feeling there is something it it that when it blinkers and hiccups in the cylinders at the same time that it may have led to current drain enough to show a faulty acclerator pot. i dont know if the alternator/gen would change its rate of output into the looms when a few cylinders baulk but for my limited knowledge it sounds feasable.. add to that a current use from blinkers and maybe thats what triggers the limp idle only mode.
if ive done a limp mode then a key restart, then if i get hiccups on a straight road and she wont go to limp mode no matter how much it hiccups.
meaning you get no error codes.

it is funny that one poster lionel above had the same problem requiring both loom and accelerator pot to be changed- but ive had them both changed now and still had the hiccups. i think his has been fine.. this is why i feel i have a third underlying prob.

you know i was blaming certain service stations fuels but it may be my fault for letting the tank go below the pump level just before i fill at that servo.

i ran it down to 1/4 full today also and never had the probs but i am beggining to suspect that the depth of the tank may be having its play on it.
i hadnt always been so specific with my keeping it half full as i never knew the pump got uncovered so easily.

it does seem funny thoough for the pump doesnt seem to stop the car.
i guess the pump being low or cracked or faulty could stop enough fuel for one or two cylinders to miss but i always thought that this pump was low pressure and only a small amount of fuel got sent to the injector from the lines. as such air bubbles sounds a bit likley culprit here.
my fuel filter was changed after the prob, but worth checking to see if the rubber is there just the same. i recall screwing it tight down on the seal and when i took the old one off after the loom problem it was on real dam tight.


i will do the checks above cause i expect it to happen again. but i will also now try and fill her up and run her down to only half way for a while now. then if no hiccups for a while ( im doing an eight hour drive next friday) and on the way back i might even let it go to a quarter or less a few times to see if that throws a spanner in the works.

apparently there is no error codes for just when it missfires but yes error codes happened when it has a limp mode idle only.

so really its likley had three things wrong. for all i know the misfires may have helped stressed the wiring loom seals. i was worried about damage to the drive train once back casue it was bucking like a brumby.

im waiting almost eagerly for it to hiccup so i can throw the blinker on again too to see if i can trigger another limp mode and have it error up to maybe tell me to change the accellerator pot/part again or something else atleast.
that will give an idea as to the pot being faulty at all even.

ill be back to tell what i find soon. thanks again everyone.

one more question of interest, why is there a loom that has been terminated with a male or female part but have nothing plugged into it in the engine bay up near the drivers main window? it sits there empty on the white paintwork near the hood hinge area?

A good question! They said they had "replaced the wiring as well as the throttle pedal". I do know they needed the vehicle overnight, as they had to remove & replace a quarter panel as part of the job, so that implies a bit more than just the throttle pedal, I would think.

The other things they said, was that they had experienced a few cases of "faulty connections" to the throttle pedal.

All I can say is - thank God it was all under warranty!

Cheers,
