Funnily enough My father mentioned today about finding another ECU and trying it, I may just do that. I tried looking for an ecumate but from what I gather the guy who made them has no stopped or retired? I’m determined to get to the bottom of this issue, it’s certainly taught me a lot that’s...

Update, was driving along today when all of a sudden it misfired badly for about 2 minutes, almost like I’d gone through a huge puddle and got the dizzy wet, instant smell of petrol at the same time. I dropped it into ‘N’ (neutral) and it revved freely, no misfire, back into ‘D’ and the...

Hi folks, haven’t had chance to test O2 sensors yet but I have given the issue some serious thought and have some info that may help you to help me. Not long after owning this disco I had a rattle which sounded like gearbox, it turned out to be the right side cat. Leads me to believe that O2...

Just looking for the O2 sensor test procedure, can’t seem to find it though. Looking in the V8 section.... Edit: Found the O2 test procedures :-)

When I fitted the AFM I disconnected the battery for a few minutes and reconnected after the AFM was installed. Would that reset the ecu or is there a certain procedure?

Ohh right, I’ll be honest, I didn’t know what the condensor did! New fuel filter and air filter isn’t that old but I have tried without it too.

Thinking about it I haven’t changed the coil condenser, couldn’t find one for a disco. I do have a new Lucas condesor for a 2.25 series engine though. Are they the same? Could the condensor cause the idle/cut out issue?

Thanks for the reply. I changed the ignition amplifier (Lucas) with no noticeable difference. Haven’t checked O2 sensors though, will try and find how to do that and have a look tomorrow. Out of curiosity how far away are you? Would covering fuel costs and lunch at my local pub persuade you...

Ahh well, it was nice while it lasted!! So, it cut out again this evening but with a difference.. This time I could ‘feel’ something wasn’t right, when coasting (its an auto, rolling along in ‘D’ with no revs) it wasn’t hanging on to the revs, revs would just drop to 1000rpm or slightly lower...

I did test the old one and voltages read as they should which was very odd, I followed info found on various forums for voltages, the aulr I think was one that was helpful. After I’d cleaned the old one it made a little difference and was fine for a couple of days then it started poor idle from...

Oh indeed! I’m that keen to try it I’m going shopping with the wife! Haha

AFM came in the post yesterday not long after posting the above. I removed the live battery cable from battery, (I’m told this clears any faults the ECU has stored) and fitted the AFM. In fitted it to a warm engine, after starting back up it made no change whatsoever. After leaving it to cool...

Back again guys, still with issues! Hasn’t cut out on me so much, only once infact. I’ve cleaned the AFM and the vacuum advance which was seized solid! Now I have a slight misfire from idle to 1200rpm and an iratic idle when cold, idle improves when the engine is warm. My next step is to test...

Haha, well I don’t own horses, it’s my job, I’m not the gaffer just yet lol. However I did have a very tidy L322 RR and sold it, repair bills were horrendous and it was in and out of the garage every month with suspension issues. I’d buy Toyota over RR next time I think.

I can relate to that very well indeed as I breed thoroughbred race horses for a living haha!

After testing voltages yesterday, cleaning the plenum and cleaning the AFM today it has ran as sweet as a nut! Not once has it cut out or idled iratically. Maybe i disturbed a wire at the AFM or TPS, or maybe the third time cleaning the AFM and plenum just did the trick, who knows?! For now (I...

A very interesting read Capo, thanks for that buddy. I may go ahead and check the base idle as a matter of course, it hasn’t been tampered with before but I guess over time tolerances change and it may want adjusting. I’m very tempted to go ahead and replace the AFM, I’m pretty certain it isn’t...

Any advice on my AFM results?

Ahh, hang on a moment, I tested my TPS with ignition ON and got the reading above.

So with 4.84v it is pretty safe to assume that the TPS isn’t the issue then? I should also add here that I’ve removed the plenum and cleaned thoroughly, I did do this a couple of weeks ago but only gave it a half hearted attempt. This time around the idle seems to be more stable, sitting just...
