850 petrol too weak at idle

dan_burdock · Dec 9th, 2004, 11:10

My 850 t5r has been sat in the garage for the past 2mnths, having purchased a £250 mondeo as a work horse. Last night I shelled out and bought road tax, I had forgot how powerful and smooth the volvo was to drive. I had some work done on the car just before I took it off road. The PNP switch was replaced. I have not ran the car on a long run for a good six months. Last night I took it on a 50 mile ish run and on the way back, I got the upside down triangle warning light. I got the codes and in the haynes manual it said petrol to rich or weak at idle.
Is this a common fault as most of the faults I have had on the car seem to be common. Any ideas?

Thanks in advance Dan

I got that code when I had a vacume leak. Check all your hoses and vacume pipes.
