I know, it was a good link you sent me, and I've enrolled in the forum, should be quite useful to Mark too.

Re: Yet another adventure....... Peugeot 407 GT Coupe
Mine misses a bit when cold but is perfect once warm. I've got the chance of a coilpack it's just getting over to pick it up. There's a few jobs to do but that'll be after the winter.

Re: Yet another adventure....... Peugeot 407 GT Coupe
That's the forum I got my coupe off Steve, a great forum with plenty of info and guides on the coupe. Once the winter months are out of the way I'm wanting to replace all the shock absorbers and springs and while it's in bits check/replace anything worn or tired.

Re: Yet another adventure....... Peugeot 407 GT Coupe
Unlikely to be the coil pack if it's bad when cold and ok when hot, ES9J4 coil packs usually either play up all the time or if temperature sensitive play up when hot.bxzx16v wrote:Mine misses a bit when cold but is perfect once warm.

My previous Xantia V6 had an intermittent single cylinder misfire when started cold that went away within 30 seconds and it definitely wasn't ignition related, as the entire ignition system was replaced...
Never did find out what it was before the car went but I suspect it was a sticking valve or a misbehaving hydraulic tappet or two as nearly every other possibility was ruled out.

Re: Yet another adventure....... Peugeot 407 GT Coupe
Thanks Simon I'll get it onto a diagnostic to see if that can throw anything up. It does run sweet when warm and will really get a shift on when needed.

Re: Yet another adventure....... Peugeot 407 GT Coupe
I'll bet you anything you don't see any codes relating to misfires - I never saw any on mine even with a severe misfire. The ECU is too primitive to detect misfires.
Has it had an oil change, and if so what kind ? Both sticky valves and misbehaving hydraulic tappets may improve with a good change of synthetic oil... (10w40 IMHO, I wouldn't use anything thinner)

I'm going to presume then that the ecumenical in the later 407 is different as Peugeot Planet definitely show a misfire ( pictures tomorrow).Mandrake wrote:I'll bet you anything you don't see any codes relating to misfires - I never saw any on mine even with a severe misfire.

Re: Yet another adventure....... Peugeot 407 GT Coupe
It had a service at Peugeot earlier this year Simon, I'll have to check the bill/history to see what oil was used.

Re: Yet another adventure....... Peugeot 407 GT Coupe
Why not use some nice fully synth 5w40 or 0w40? If it's fully synth and in an lpg car it will be stayng very clean compared to most oils and the thinner cold grade is better for cold startup as well

The ECU is too primitive to detect misfires.
The ES9J4S ECU has a misfire monitor, the ES9J4 does not.
One reason why is the ES9J4 has no cam sensor, so it doesn't know which cylinder (out of a pair) is firing or not firing as the case may be - injectors and spark plugs are fired in pairs.
An ES9J4S fires injectors and spark plugs individually and does have a cam sensor thus is capable of narrowing down a misfire to a single cylinder.
PS I'm assuming Marks 406 is a D8 with the earlier ES9J4 in it like the Xantia.

Too thin an oil leaks past worn leaky hydraulic tappets too easily preventing them from pumping up.KP wrote:Why not use some nice fully synth 5w40 or 0w40?

I actually put some 10w50 synth in that car as a last ditch measure for the valve gear issues about two months before I sold it - I think it was actually starting to help too...

Re: Yet another adventure....... Peugeot 407 GT Coupe
I've read that mixing semi and fully synthetic oil can cause problems as well. Be worth doing several change in quick succession if going from semi to fully synthetic.

Re: Yet another adventure....... Peugeot 407 GT Coupe
It is the earlier D8 Simon, last serviced 7/2/14 at 95664, it's just done over 1k since. It has been serviced using 10/40 semi synthetic for a good while now.

Re: Yet another adventure....... Peugeot 407 GT Coupe
It's been on semi synthetic for a good while too, I will leave it at that for the time being. I had a Renault 25 V6 turbo years ago and that was on fully synthetic, it used to drip oil like no one's business.
