P0302 Misfire Problem

[Will Eastman]

The 182 has been idling a little rough (mainly from start up), and the engine warning light has been going on and off. It has now started flashing so I descided to get the code checked.
It put out...
-P0130 02 sensor circuit (bank 1, sensor 1)
-P0302 Cylinder 2 misfire detected

I have just changed the plugs, coil and leads. I have read a lot of people saying it would be the injectors so I let the car idle and pulled each injector in turn. They each caused the car to nearly stall. Does this rule the injectors out then? Any help would be much appreciated.

One way to test it would be to clear the fault code, switch the injectors around so that the injector for cylinder 2 is now on either cylinder 1, 3 or 4 and see if the misfire then moves to that cylinder.

it's the injector, just replace it.

Why would the idle still get worse when pulling the plug off it? Can it be that it's just not firing 100%

 

[bloke]

yup, measure the resistance if you want.

I did got 16 on most of them then 13 on the dodgy cylinder. Although that was the third cylinder from the gearbox (isn't that cylinder 3)?

Yeah that would be cylinder 3 ( 4 - 3 - 2 - 1 )

that's number 2 and your dodgy injector. £33 from euro

I'm sure injectors are cheaper than that from Renault

 

[Will Eastman]

Is it advised to replace all 4? Iv heard the others will go shortly after one is replaced?

 

[DannyR]

No just one will be fine

Have got £50 in my head from reno, could be wrong though? I grab them from euro as they are only a couple of minutes from me

 

[Will Eastman]

Think I might get a set, its turning into a costly birthday present for my car

Prices from Renault are -

You would be best to buy a new sealed genuine OE from Renparts on ebay for £32.50
