Hi,
I have a 1.9 litre and unable to fix a running rich problem.
As a matter of course I have replaced spark plugs, distributor cap, rotor arm, all leads. I have also adjusted the small screw controlling idle but my understanding is this ONLY controls idle so should make little or no difference to general running. Sure enough, it didn't. In front of you when you lift the bonnet is what looks like a black fusebox which is sealed by what looks like black bathroom sealant. I have seen videos where people have removed the lids to adjust the gears inside controlling the mixture. Seems like a reasonable idea BUT why did Peugeot seal it in the first place if the lid was meant to be removeable? Surely they'd have used screws? Having spoken to several people I've been advised not to touch the mixture gears. Peugeot set them and they're not intended to be adjusted. OK, that's all well but my car runs like **** and is thirstier than she should be. Which leads me to this post. Has anyone experienced the same problem and does anyone know how to fix it? Thanks
