Peugeot 307 XSI - Fuel System Monitor "Not Ready" - IanT1974

Hi,

I have recently purchased a 307 XSI, it had an itial problem of a misfire but have replaced the coil and plug, so thats all sorted.

But when i first start it up it runs a bit lumpy and gasy from the exhaust. Once it has run for 10 minutes it settles down and everything runs ok from there.

I have checked it with a small scanner and there are no fault code but the Fuel system monitor reports "Not Ready" all other sensors are reporting "Ready"

Any ideas, tips, suggestions would be helpful. i have had a mobile mechanic look at it, he said its running ok, but wants to give it an oil change etc?......... Could this be right?

Cheers

Yes,he could be right.The cold start misfire on some of these 307 models is caused by the hydraulic tappets "jacking up" and not allowing the inlet/exhaust vales to seat properly and thus cause a running issue.Peugeot do revised tappets for these ,but not a cheap job.Get the oil and filter changed and use a good quality oil to the correct spec.hth

Thanks for the advise, makes complete sense.

As the car is 10 years old i think I will try the oil change forst using a good quality oil :-)
