3.2 running grumpy

[TheBoy]

At  next meet, if anyone is willing, I might be inclined to swap throttle body...

Think it might have got to that stage. Just swap bits until something changes. :-/

Right, thanks to Albs, new ecu, transponder and chip installed. 

The mystery deepens... swapped the above over, no emmissions light but spanner light on

Took car for a blat and goes like a train and seems to idle better but spanner light off after 100yds, emmissions light back on arse.

Pedal tricked the codes when I got back and got the following:
in order
1. 1500 throttle failure.
2. 0120 throttle position.
3. 1612 immobiliser no signal (forgot to plug transponder in before trying to start ).
4. 2106 CanBus failure to connect to transmission (haven't fitted the autobox so no surprise).
5. 0300 general misfire.
6. 0305 missfire pot 5. (might have mis counted)
7. 0300 general misfire.
8. 0306 missfire pot 6.

Not sure what Albs' breaker died of, so don't know what issues are new or old though some are obvious, ie gearbox.

Also got the cruise working with a new switch, but now not working again.

Going down to Lyndhurst tonight, so car will have a decent run to settle down. :-/

(I'm thinking possibly a wiring upset for the number 6 injector :-/)

Breaker died of a seized bottom end. I dont have any knowledge of what problems it may have had before that though. :-/

(I'm thinking possibly a wiring upset for the number 6 injector :-/)

Possible, although the ECU should detect that and throw up a code.

Worth swapping the injector with another pot and see if the fault moves?

Did the breaker have cruise? Could be that cruise is not configured on that ECU.

[Kevin Wood]

.. and if cruise is configured, likely the auto/manual gearbox mismatch is disabling it?

That was my thinking, was working fine with the new switch before I swapped the ECU. Engine probably now thinks that it's on a bench.

Swapped injector 6 with number 3 iirc whilst trying to investigate initial problem. Thinking that if accidently earthing that injector plug had frazzled the old ECU, possibly did the wiring at the same time. :-/

Incidently, Emissions light is still on permanently, could the gearbox mismatch do this?
Also will idle alot better that it was, even if left for 5 mins. Before was missing really badly and hunting all over the place as the ECU tried to make it idle. Now idling almost steady, only fluctuatin 50 ish rpm rather than 300 ish. Though after a while the light flashes for a 10 seconds or so ,then stays on.

Right...

After a couple of days the car was back to its usual self, ie moody as cufk.

Worth swapping the injector with another pot and see if the fault moves?

Took the inlet manifold off, stripped the injectors off and cleaned everything, popped it all back together. No improvement. Busy working Friday night and one of the injectors sprang a leak

Got a complete 2.6 inlet assembly from Steve at Heathrow

Totally identical to 3.2 one as it happens, (compared side by side off the car). All back together, and...

Still runs rough if left idling for more than 30 seconds. switch off and on again seems to be the only cure, but that has ruled out the injectors and injector loom if nowt else. :-/ and I now have a spare manifold for lpg nozzles.

Can get a new engine loom for £100, so wonder if that might be the next step? Or am I on a hiding to nothing? :-/

[Kevin Wood]

Worth getting it on a tech 2 to see if anything obvious is changing when  it runs lumpy, IMHO. There must be a clue in the live data.. :-/

[05omegav6]

Will just have to put up with it 'til the lakes. A poly barrel of WJ Kings' finest to the person/peeps that solve it me thinks.

Still managing 25mpg whilst working which is ok. :-/

[albitz]

Re cruise. Breaker was an elite, and pretty sure it had cruise - Istr selling the stalk about 3 months ago.

Darn! I wish I was going to the lakes. [smiley=beer.gif]

I'll try and save you some

Have finally found the issue with this I think...

I've removed the plug from the 246 coil pack and attached a replacement one along with another 5" of loom. Whilst doing this I found a loose earth wire, which I have re attached.

Did a run upto Gatwick and back (26 miles) and no sign of the EML, the engine was running for approx 1hour (including a drive through breakfast).

Left the car for a bit and on restarting the light was back on

Pedal trick produced 0100, 0300, 0306, 0300, 0306.

So we have a general misfire, a misfire on pot 6 and an iffy MAF sensor.

Engine gone all lumpy again

Maf disconnected = no difference As for the misfire returning, that could be my soldering, but might only be that light stayed out due to ECU being unplugged whilst soldering, and now readjusted itself

Looks like the loom could be next for changing

Where did these coil pacs come from Al?
