Hell!!

I heard they were doing one, and I thought any electric version fo the mustang was a horrendous corruption of the breed.... (yes, the future is electric, no getting away from that, but as far as I'm concerned Mustang, Corvette etc should be the last IC-engined cars standing, once 99% of all new cars sold are EV in 2040 or whenever.) American muscle cars are, by definition, supposed to be offensive, and against 'society', like a Rock song - making a 'nice' rock song, about trees and happy dolphins, sung by. 

But that?? It's marketing in charge, clearly.

I'd love to imagine how the initial briefing went - "right, guys, we want to do a 5 door hatch Mustang, and it's an EV" and every designer who really loves cars, and the passion they can evoke, and the spirit and heritage, and noise refused to be a part of it and walked out the door... Those that were left, who weren't really fussed, 'so long as it pays the bills'-types, they designed the car.

Wondering if you may have an intake air leak which is messing with the idle speed/ mixture, done any live data / check fuel trims ?

I have considered vac / similar leak. The plenum's been off doing the DIS pack, and this did manifest itself after then... I am very aware that unless spot on, an air leak is very possible upon reassembly.. Might go over the engine with some carb spray, see if the revs change, tomorrow, too.

Tomorrow I'm going to check connections for alternator and earths.

Possible exhaust blow, yes, however that's just gone on last week, after the other one collapsed after 7 months.  ::) As you can see, Ive had a busy few weeks. About 23 years of car issues are happening all at once over a 2 month period.

Wish the car was just a touch cooler when you arrived Dave, would have been great for you to see the issue for yourself.

Postulation - if any of the wires to the DISpack briefly lost contact, would this just manifest itself a single, momentary misfire, or would this leave no signal to the ECU which would suddenly throw a paddy and just cease functioning? hence the stall?  ???

That all said don't know why that should manifest itself only when cold.  :-\ so probably barking up the wrong tree.

Fitted the Dave the Builder relay (I think I'll sharpie marker the name on it for future generations to marvel over when Time Team dig up my Omega) and she didn't do 'the thing'....I think she's still a bit warm from the previous run (still under 90o) didn't feel quite right, added all the load (lights, heated everything) and the idle wavered a touch.

Blipped the throttle, to the floor very fast, flooding the engine, and the revs died to 150rpm but she recovered immediately, presumably the inertia of the engine still spinning. I'd suggest that 'near stall' isn't any relation with this problem, that's just any cable-operated throttle would do that, presumably an ECU controlled drive by wire throttle wouldnt do the same.

Acid test will be tomorrow morning when shes been sat all night, I'll go round the block - I mean fingers crossed it's the relay. But I'm still not convinced. Happy to rule it out though.

Well... get ready...

Checked new battery voltage before fitting 12.5, so decent enough there. Went for a spin (engine temp reading just on gauge, but sub 90o, just to get some charge into the new battery...did it again!

Turned over very quick (a touch quicker than on the original Vx battery, and perhaps a smidge quicker than on the Varta/Ovlov battery) no hesitation, but went to top of the road and... engine just died. Headlamps only on, then added some more drain, went round the block a couple more times, didn't do it again.

For me, next step will be to fit the Dave the Builder relay, give her half an hour or so to cool down, then try round the block again. Will try some multimeter testing of the 'old' relay, whilst it's off, too.

Anyone else got any suggestions?  ??? I'm all ears!  :D

Ooh, didn't even know such a thing existed! Ta Nick  :y

Ok chaps, just done some more bits. I have changed the throttle pedal adjustment along a fair few clicks, now the throttle feels lovely and responsive, I am the only one that would touch that/know how to, so don't know if they 'slip' over time. Very odd. There was about 2inch of travel before throttle actuated before, the car felt sluggish, but that wasn't really the issue, so left it at the back of my mind.

Went round the block a few times, with all systems on, tried going in and out of D, N, P etc many times, tried to make her do it, nothing...

 EDIT:

Dave the Builder just turned up. Brought a purple relay  :D did a wee code reading, nothing of note there. Car starts perfect, and no issues present. As per the pattern, nothing shows up when the car's warmed up. Best best I think is to await my battery (here in an hour or so DHL says) get that on, Miss DBG gets her car's battery back, and either give her another run, or even wait until overnight, then (with new battery) give her another go.

Will check didn't want to leap in and start changing variables. I'm going to check the youtube for relay testing shortly. After coffee.  :)

Right... 

1) Done the MAF unplug thing, still did the stall thing. Again, as I engage D from N or P. I'd suggest this is a marginal rev drop, combined with already-low voltage going to the ECU drops by that smidge more, which cuts the ECU out. My 'theory' only.

2 a) Definite appreciable 'rev waver' when engage lots of draining systems.

2 b) Specs of the 'good' volvo battery on a 1-2 mile journey to work and back are...
(no voltage recorded before setting off)
12.85v upon arriving at work
12.53v before setting off
12.87v back at home.

This morning
12.43v after a night sat
12.25v engine running with all the load. (H'lamps, heated seats, fans, heated rear window)

just done a 'cold start'
12.43v before cranking
10.70v on cranking (oh started instant, no issue by the way, but engine was 920 as only run ten mins previous)

3) Just a side observation.... the throttle pedal has a fair amount of 'floppy play'  :o before 'biting' could this in any way be a contributory factor of this? When I removed the plenum I actually left the cable/adjuster in place, so is shouldnt have changed position. But could 'tightening this up help matters? Silly thought?

Anyway, not MAF, shame as I have a spare!

After giving some positive words to Halfords, I helped a new work colleague change her battery the other day. She got the (undersized  ::) ) battery from Eurocrapparts but when I opened the bonnet I said "what's that?!" There was a headlight bulb sat floating around on the scuttle! Turns out Halfords had sold her two bulbs and their free fitting service weren't able to install one (there is a clip missing, so the bulb falls out the lens, I bodged it so at least she new has two headlamp bulbs pointing forwards but told her to source the proper clip asap. But one can only presume she got charged for two, the second left essentially 'outside' in the rain for several weeks until I spotted it!

Ohhh dear, Halfords.

I have had good results from reverse flushing the matrix. However I agree with Dr Gollum for best results change the matrix. Sounds like just airlocks, though you may be lucky.

We haven't no. First of tomorrows job is (nice and cold, low battery voltage) to unplug ye olde MAF and whizz round the block..

Taa. Will get digging how to test them, then..

Oh. Update, drive home from work, she stalled / died again. Realised it was as I sat at roundabout, and engaged D, after being in N. Tried then several times on rest of journey and couldn't make it do it again. Odd one...

Oh, knew they were both purple, in truth no idea they were identical components! Ta. Will try that.  :y

Omega General Help / Re: Leak somewhere and carpet removal
« on: 18 November 2019, 19:13:33 »
My rear footwell is constantly creating itself a small lake, so watching this with interest. Have unblocked all the drains/scuttle so no idea where mine is getting in, so can't help you OP  :-[. Usually the driver's footwell only when scuttle blocked. My driver's footwell is fine, but rear passengers behind driver is sodden.
Scuttle blocked.

Water drains to the lowest point...ie the rear footwell on the Omega.

Can also be rust related and would recommend removing the rear carpet until you find the leak. Failure to do so will result in needing the floor welding in the near future  ;)

Scuttle drains have been thoroughly cleaned on regular basis, I am suspecting a rusty hole somewhere is the issue on the firewall. And yes, carpet is out, as you say, for rust /mould prevention!
