So then, it’s been nearly two days and no issues, no misfire, no cutting out. One thing that still doesn’t seem spot on is the idle from start up (cold engine/morning start up) for the first five seconds. It will start pretty much straight away, no misfiring or spluttering but the idle hovers...

It appears I have fixed the cutting out issue, AT LONG LAST! Haha I got a recon exchange alternator fitted that, I also picked up a coolant temp sensor, replaced that at the same time, been fine all day on two journeys and being used around the yard. I’d like to thank all of you for your help...

Daz, I’d use eBay and look for the parts with free shipping :-)

First bit of advice would be to change all ignition components, plugs, leads, dizzy cap, rotor arm and coil. Also clean every electrical plug under the bonnet, I cleaned mine then sprayed with contact cleaner followed by a spray of WD40. Then see how things go from there. I’ve just ordered an...

Alternator ordered, just awaiting delivery. Definitely no spider in my vehicle, pulled the radio and had a look earlier on today. However....!! The misfire appeared again this morning on start up but cleared with a blip of the throttle. Going to order temp sensors (both) this evening...

Ahh ok, I’m that case I don’t have a spider, thankfully! So would a dodgy alternator cause the cutting out issue I keep getting? Edit: It just randomly cuts out, engine checkmlight shows and then it comes back to life and drives like nothing has happened! I’m obviously chasing more than one...

Thanks for the reply. The battery light has gone out now but still now rev counter. I’ve cleaned all connections on alternator and battery along with Earths, still no improvement. The alternator is getting red hot, can’t touch it! This is even when engine is cool, so a short time running and...

Things seem to be getting worse! Driving along and it cut out, fired it back up after several attempts, it now has the battery light showing on the dash, no rev counter working and a whine which resembles a supercharger from under the bonnet! I’m thinking alternator?? Thing is it’s still...

Update... Cleaned connections to fuel cut off switch, and cleaned the fire trap breather and hoses. Also cleaned and inspected connection to charcoal filter. As matter of course I removed the stepper motor (it’s only a week or so old) and cleaned. I did notice when removing it that it wasn’t...

Started up this morning, idle ran slightly high as you’d expect from a cold engine, selected reverse idle drops to just below 750rpm, feather the throttle and idle drops to approx 300rpm before picking back up and driving. Completed manoeuvre with no other issues, select park and idle sits at...

Thanks. I’ve looked through that manual twice and read that the base idle procedure is found in the ‘fuel’ section (19) but I’ll be damned if I can find it! Need to look again. After reading I’ve found the location of the fuel cut off switch, I didn’t clean that connection so that’s another to...

I will double check :-)

Thank you, I have Forte fuel treatment/cleaner in at the moment, I’ll give redex a try afterwards. Never thought about cleaning the flame trap breather, I did remove and inspect the hose earlier on today though and it was relatively clean. I don’t have a manual, is there anywhere on this forum...

There’s 3 Lucas TPS on eBay at the moment, take a look :-)

Started up and parked the Disco tonight, backing on the garage I shifted from Drive to reverse, feathered the throttle and it cut out again. Started back up quickly on the key and idled high (just under 1000rpm) for a moment and then dropped to just under 750 rpm. I continued to reverse with no...

Update! I found the cause of the misfire... Injector plug connection was badly coroded, seems to have cured the misfire anyway. However... I now (did) have an idle issue straight after curing the misfire, It’s intermittent, if I’m driving along and then pull up in traffic or at traffic lights...

In different words you’ve said pretty much what my father said to do haha.. I’ll try and make some progress this weekend and see what the verdict is, I’ll keep you posted. Thanks for your help so far :-)

My old man suggested cam! Going to do ancomoression test tomorrow and see what the results are. Any ideas what compression should be? Searched for my Haynes manual but can’t find the damn thing, ha!

Update... Replaced all ignition components, plugs, leads, rotor arm, dizzy cap and coil, used Lucas as generally they make good parts. Misfire is still there! I also replaced the stepper motor as the idle was up and down, this didn’t change much but it helped, I’m assumingbthe misfire is...

As above, 95 3.9 V8 with a misfire under load. So far I’ve changed the plug leads which made the issue worse so to me it’s definitely an ignition issue, tell me if I’m wrong. I know Rover V8’s can be plug lead fussy and the brand I used is all my local car spares can get. There more than...
