It reminds me of the 1300 cc Renault 8 Gordini - 4200 RPM minimum to be happy (and on the cam).

My Mi16x4 has what i was told regarded camshafts, it also hates low RPM, anything under 2000-2500 rpm just doesn't make any power, but above 4500-5000 rpm when it get on the camshaft it pulls harder and harder, with the close ratio gearbox it was a pleasure to drive it hard, until the transfer box went out then i convert it to FWD and become understeering tire frying POS. I do miss driving it, maybe one of this days, i'll find a deal on a standalone ECU and that will motivate me to get it back on the road.

Wow, hard to believe my thread has reached 10 pages...I guess I'm a true Peugeot owner now, ha...

I'm hoping to hear from the shop in the next day or so, will update here what their findings were...

The car may be done today, they found a small vac. leak, maybe 2, waiting to find out, will report back...

Ok guys, got the car back from the shop today...some interesting findings...

First of all, they found a couple very small vacuum leaks via a smoke test and then repaired/replaced the lines. Ok, good start. Second, they ultrasonically cleaned the injectors, so that's great too. And finally, the last issue, the CEL...still on, ha...

They think I might have a bad ecu, and I think they're probably right. We're at the point where just about everything has been replaced, and this is about the only conclusion to come to at this point. They couldn't even clear the code (52)...

I still have the spare ecu from the guy I bought my car from, going to test it again and see. There were still other issues with my car the last time I tested the ecu, so maybe now that everything else has been done, this will be a better time to test and be able to trust the findings...

Having said all this, I can honestly say I'm at a point with the car that I'm very pleased with. It runs and drives excellent, it's comfortable, suspension and brakes are great, the exterior and interior both cleaned up incredibly well...it's really turned into the car I hoped it would be...

Going to continue to drive it a lot this season and monitor everything, as well as test the spare ecu. Worst case scenario, it doesn't change anything and I have an occasional intermittent cel light coming on and off. Given all the effort thrown at the car over this, if that is all that remains, I suppose I can live with that...

I washed and spray waxed the car and cleaned the interior today after getting the car home, and then took it on a long driver this evening. Some photos because why not...

It's great to have it back, I actually really missed it...

And on an entirely different note, and while I know this was covered earlier, here are some photos of my glovebox arrangement. You should all do this, as I imagine your gloveboxes are all as blown apart and rattly as mine was. Nothing left to squeak or rattle when it's all gone inside...not to mention easy access to the underdash componentry...that is if you can live without a glovebox...

Ok all, just as I thought the car was "done" as far as maintenance and repairs, a new one (2 actually) cropped up...

It's been a custom since working on this car to check underneath before and after each ride to make sure things are ok. Well, the other day I noticed the driver side inner cv boot let go and much of it's grease all over my otherwise cleaned up undercarriage. Not only that, but I noticed the inner on the passenger side also has a small slit. Yay...

Oh well, put a call into the mechanic, he's booked a couple weeks out, so in the meantime I cleaned everything up as best as I could, re-packed with some bearing grease, and found some self fusing silicon tape I had and wrapped the hell out of both sides. Should be good enough to get me to the shop...

Edit: Ordered all 4 boots from Peugeot Holm, glad to finally do some business with him...

My silicone wrap lasted a couple days, boots should arrive by the end of the week, r/r scheduled for early next week...

I've driven months with ripped boots, the inner joints are much more robust, don't be that concerned, water is the biggest enemy, i've washed my joints with gasoline and use graphite grease. I'll attach pictures from the last axle i changed boot on i think it was on my 607. The 405 have some of the easyest axles to take apart they don't have C springs at the end, onece you release the boot the joint can be pulled off by hand, i advise you only remove the outer Cv joint you'll have access to change both boots, if you have dirt and grit then you'll must clean them, the inner sometimes stay together, sometime the needle bearings can fall out. And you should drain the gearbox oil, the level is above the axle holes, simple drain and refill when done. I hope this helps.

Goce, thank you very much, this is certainly helpful, I will show this info. to my mechanic. While it's nice to know that I can go for a while without doing this, it's not really my style, plus he has availability next week, so good enough reason to just knock them out now...

Different note, I did try the "spare" ecu that is was supposedly tested good, based on the shop's determination that I may have a bad ecu (after cleaning the injectors, and finding/fixing 2 very small vacuum leaks, they were still unable to clear and keep the cel off). The messed up part is that this ecu actually made the car run quite terribly, even the stumbling and hesitating came back during the test drive. That had not happened in a couple months, and it was not fun to experience again, (peugeot ptsd...). I guess maybe the spare ecu isn't good after all???

In any event, I put my original ecu back in and everything seemed fine again (of course, still have the on/off cel), but I did foul the middle 2 plugs again when that other ecu was in. So again, I just put 4 new plugs back in, and everything seems right back to where it was...seems I'll be living with a very nice running and driving Mi16 that has the occasional cel while at idle...

Maybe it's not the ECU but the loom, it's easy to find what's wrong when a wire is just cut but bad grounds, corroded wires, damaged connectors or dry solder joints that's another story.

If you test for continuity you find it's all good but as soon as you try it the thing is dead for a few hours then back to "normal" on the continuity test. It can also work like a charm half the time and not at all the other half.

That's a great point and I started to think the same thing too. That might have to be a winter project, diving into something at that level...
