I cant belive this car

[djvass]

Hi all,

For thoes of you who have read my other posts and have read what i have changed on my vp, it is just gone and done the same thing.

I have changed CAS, INJECTORS, PLUGS, LEADS, DFI, AND FUEL FILTTER as well.
Sitting at the lights on my way to work on friday she decided to just stop again. Had to push it to the side of the road, lucky for me i still had the tools in the car from before so i did a fault test and it came up as 41 CAS couldnt be as it was just changed 1day ago. So pulled the engine fuse out so the computer would reset and sure enough it did. Did the fault test after that and it came up code 12 everthing ok. Drove it for about 1k and then started to sutter and cough and miss stoped on the side of the road again and did the process again this time wouldnt fire at all. Anyway left it there went to work got a guy from work to get me. Then on the way home stoped to see if it would start and it did no probs at all and i drove it home without it missing a beat. Now i need to see if i may have missed something or you guys no why my car is doing this.

Thanks
Dave

It's not unheard of to have a faulty CAS. Did you get the correct one?

[djvass]

yeah m8 had my mechanic come and do it for me as i didnt have a big rattle gun to do it. Just took her for a run again and noticed it is fine driving at turtle speed but when i put it under load it doesnt like it at all.

[VrWagz1]

Always being ok when its cold and stuffing up when it gets hot suggests to me that it is possibly the cas again. Sucks but might be worth swapping it out again.

[djvass]

na plays up when it is cold and i put it under load straight away.

check the wires to the cas aswell.
If the diag test say there is a problem with the cas then check wires and if they all ok change cas again.
I know it sucks.

Swap the ECU for a know good unit.

[Doctor Bob]

check the fuel pressure

[djvass]

could the harmonic blancer be sending a wrong signal to the cas?? So what i am saying could the harmonic blancer be the problem??

If the rubber is split in the HB then yes it could be. Do you get any sort of clicking irregular type noise?

PS also it was the ECU in my VN that was causing the car to die all the time. (and I replaced the same list of bits you have) The ECU was the last thing I changed - and it has not stalled now for 6 months.

I had the same type issues, exactly the same.

as soon as its warm or u floor it it coughs n dies...

found mine to be a shonky carooded plug on the 2-wire Coolant temp sensor (not the single wire guage one)

Can u smell a strong sense of fuel and a lot more than just the normal black round the zuast?? seem like a Old carby car running far too rich (if ur not too young to remeber that :P)

i tried cleaning the plug up and putting a new sensor in, worked sweet for 2 days then it went again, so then i pulled the plug out snipped the wires, took it inside and apart, soldered new wires and tinned up the terminals, then from an Irrigation shop i got this Goo that they use on sprinkler solinoid wireing terminals (lot like KY-Gel) Bawhahah and its an anti corrosive and its water proof smeared it with that, and put it all back together with 3 layers or heatshrink over the joins and she's apples. and i now have a spare DFI and COils, CAS, Fuel pump, ECU and altinator. all for the sake of a hours work and $40.

hope this helps.. if you pull the blue plug off and u look at the terminals they will have greeny white corrosion on them. just give it a hit with some INOX spray, and put it on and off a few times then spray it again... then reset ur ecu and go for a spin... if still not get a new sensor there $18 and try that, if still not try my other theory... but the inox trick should keep the contact there for a few days through the carosion.

This is the type of reply i was looking for i will give this a go tomorrow and let you no the outcome. I rearly do apprechiate you taking the time to post this for me.

Thanks

ok went out this morning and just bought a new CTS cleaned the terminals with inox and put it all back together, took it for a spin and the car seems ok i am to scared to take it far atm as i will have to go too work soon so tomorrow i will give it a bit of a run somewhere and see what happenes.

[PaRaDoX]

i had the same problem, its common for it to be something else to do with ignition and incorrectly report the fault.. in my case my DFI went not the actaul sensor, went through 3 of them before they found it

if its still broke try and borrow a spare coil pack and take it for a test run (round the block many times till it gets hot helps)

actually i had this problem twice...hehe yeah it sounds like my dilema's!

[djvass]

changed the coolent temp sensor. No change stoped after 10min of driving and got me stuck again. This time i had water to poor on the CAS if it stoped and sure enough after pooring water on the CAS it fired but then did 1min up the road so now on thursday i will be changing CAS again.

[djvass]

got a second DFI unit and it still does it. Changed that first before i did the CAS the first time and it didnt help.

Have you swapped the ECU yet. I would

[djvass]

do you reckon i should change ecu's?

I have chased this issue on the wagon and the last thing I replaced was the ECU.

Mrs. uncle had a VR with an erratic, intermitent electrical fault.Turned out to be a dirt on the blades on the HB.

changed the CAS Again today and well now i have lost all spark to the engine. Not happy!!! will try and get another ecu and go from there.

Are all teh connecting wires good - have you given each one a tug to see how attached it is?

I have a spare CAS in the shed too - from chasing this problem of random stalling after replacing:

CAS x 2
DFI
Coils
Fuel regulator
Disconnected factory alarm
disconnected key lock in the glove box
bypassed the white wire to the ECU (from the ignition)
replaced the O2 sensor
replaced the temp manifold sensor
re did the earths.
Then the ECU
I had a laptop connected and recording when the car stalled. The readings said that the a/c fan was requested and at teh same time the engine readings flat lined as the car stalled. This sent me to the fan as the problem - so I disconnect the fan. Car still stalled. Replaced the ECU and the car ran fine.

The DFI unit failure gave the same problem of stalling but got worse over a few days to a complete stop. The ECU was more like weekly and would re start first kick. Ot did this for like 3 months or more.

The car is all good now (plus a greenfoam tune)

[djvass]

I am going to change ecu tomoz and see what happens.
Thanks for the info to.

when you say conection wires what ones are you talking about??

The DFI plug can be a problem as can the O2 sensor. It's a long thin connector with a 7mm bolt in the middle of it. If done up to far it can bend the DFI plug and not make good contact. (long shot stuff though)
