Megane 1.4 TCE "Check Injection" lots of codes!

[anonymous-user]

I was sitting in traffic for a couple of hours yesterday and just as I got home the dreaded "Check Injection" light came on. I read the codes this morning and get the following



Judging by the marks and gauges on the ODB cover this is not the first time it has been off. I have owned the car for seven months, I did have an emissions light come on briefly a few months ago after parking at an airport carpark for a week, but I suspected this was due to the car being moved around all week?

I have cleared the codes, my plan is to fit new spark plugs (I suspect they are originals) and go from there. I have had failed Lambda sensors on other cars around this age, so I am wondering it the one on this car is failing as well?

And advice other than "get rid of it now"?

How is the battery? - just if the voltage drops the whole car thinks loads of various things are going wrong..

It's a cheapy old Lion battery, but the car starts instantly so I think it is OK.

Looking at the list again, the ones related to the lambda sensor and one of the misfires states "Archive (inactive) so I suspect they were from when I picked it up from the airport and light came on briefly before going off.

So I think the errors from yesterday are

PO302 - Misfire Cylinder 2
P0325(1c) Knock Sensor
P1525(F3) Air Bypass Valve System

Take it for an Italian tuneup and see if they come back I guess
