Diagonistics Results...Help really needed please - Saxperience

Luke_vts · 22nd February 2007, 14:56

My car was behaving unusually (loss of power between 2000/3000rpm). So I took it to my local garage for a diagonistics test.

The results were

1.) Intermittent fault - upstream oxygen sensor

2.) Intermittent fault - Cylinder 1 misfire

3.) ECU fault code PO130

Can anyone tell me what this means? please I really am stuck

your first (before the cat) lamba sensor is faulty.
misfire could be related to faulty lambda, any answer is just a guess could be coil pack, plugs etc etc
no idea on the 3rd one, either ask the garage or phone citroen and ask them what it means.

OK so i need to replace the lamba sensor (the one on top of the manifold)

and possibly the coil pack?

Could it be anything else causing it to misfire in cylinder one?

you really need to find out what the fault code means as it's probably giving you a reason for the misfire.

Give citroen a call and ask if they can advise you what the code means.

Can someone tell me if the Lamda sensor could be causing the misfire or is that a seperate fault?

I had the same problem, tuned out to be my coil pack, Replaced the pack and the spark plugs and the problem went away. £80 for the coil pack and £15 for the sparky's!

Problem solved

My bet would be faulty coilpack causing the misfire which is then flaggin the intermittent fault from the lambda. Sparks and coilpack are your first port of call IMO

mattsaxo did ur power suddenly kick in around 2000/3000 rpm in 1st gear? the car feels very restricted through the gears, was yours the same? it feels like engine breaking in 5th gear, did u have that?

Just want to be sure before i dish out £80 on coil pack.

Cheers lads
