Ah then it’s probably an injector, you can swap the injector for cylinder 4 to another cylinder and see if the misfire moves to confirm that’s the issue.
Likely the lambda sensor in front of the cat it controls fuel trim.
The sensor after the cat is there to see if the cats working and doesn’t effect fueling.
Swap the plugs around and see if the misfire follows.
If it stays on cylinder 3 then you can swap the injectors round to see if that’s the issue.
If it still stays on 3 then coil pack.
I imagine lots of folk know this already but figured out the other day you can fit a normal hacksaw blade to a recip saw.
Real handy if you need to bend round a corner slightly to get down a tight gap.
Post a picture of the sensor as I’m not sure which one you mean.
If the radiator is leaking then it needs replacing.
The dashboard lights indicate a fault and are putting the car into limp mode hence the poor throttle response.
Swapped out the cabin filter.
New bosh wiper blades.
Fitted a new brake pedal switch as it was flagging up on the code reader.
Took it for a run down the motorway, returned 55mpg pleased with that.
Backfiring and lack of power indicates a misfire, this could be caused by any number of things but usually Injectors, Coil pack or spark plugs.
Do you have any misfire codes?
If the second sensor is the same as the 1*2 it doesn’t do anything to the fuel trim and is just there to confirm the...
So swapping the injectors didn’t resolve my issue.
At this point I was getting a bit confused as the coil pack seemed to be fine on the multi meter. So I decided to do another compression test, This came back with 200psi ish across all cylinders.
However cylinder 2 whilst it got to the same...
White oilyness is just part of these engines in my experience.
Only advice I’d give on the gearbox is remove the plastic bung before you drop the oil just incase it won’t come out.
It was annoying me so pulled the inlet off to take a look at the injectors.
Certainly looks like cylinder 2 injector could well be my issue as it’s more rusted than the others.
The likes of ecp want £70 for an injector or an eBay special for £30, I don’t particularly fancy either option...
So took it for a test drive and noticed it’s down on power and feels like it’s misfiring.
Played around with the HT leads and narrowed it down to cylinder 2.
Swapped the spark plugs over just in case but same result so figure it’s one of two things the coil pack or an injector.
The injectors...
Best thing and worst thing about cheapo clios is how cheap the parts are.
Engine fully stripped down for the belt and water pump change.
New pump and belt installed.
Engine built back up and first run, always a nervy moment no matter the number of times you’ve done it.
Took me a second to...
Gearbox oil changed, getting the plastic bung out was a complete nightmare, stupid design. But the existing oil looked decent so has been changed at least once in it’s life.
Then swapped the plugs, cylinder one was full of rust which not ideal but dry so I suspect some water had got in there...
Stripped off the scuttle panel to get to the top mounts and was met with a nice pond and a blocked drain.
Pretty amazing amount of dirt in there so it must’ve been blocked for a while.
Got to say I’m impressed with the generally lack of rust but wire brushed a few bubbly spots and gave it a...
Moving on I ordered a new thermostat off eBay for £17 and picked up a bottle of type e coolant.
At some point this has had a coolant change to red coolant so when I uncovered the thermostat It was a bit powdery.
Coolant dropped some went in the bucket most went on the floor.
Cleaned up the...
I’ll be honest I’m not really sure why I’m making this thread as it might not go anywhere but maybe it's interesting to someone.
Whilst my beemer was out of action I picked up this 1.2 mk3 as a cheap run around, The paintwork is awful but mechanically it is in pretty good condition and also...
