Technical Cylinder 1 missfire and check engine light on

[Zachwoolston]

Hi I recently purchased a fiat grande punto and after buying it the check engine light came on. Got the spark plugs swapped and it went off then came back on after a couple days. Then a few days after that its come on again. Took it to a garage and had the coil and leads swapped but again having the same issue of it come back. When on the obd scanner it said cylinder one missfire and random missfire. Has anyone had similar issues and how to fix!

The injector in cylinder 1 could be partly blocked or otherwise faulty. Its hard to say for sure though.

I've had injector cleaner through the system so I'll have a look into it being faulty

If the garage changed the coil pack (1..or 2?)

It was obviously faulty,

So. Plugs, leads and coils all new..

There are other potentials for misfire

Which engine is this?

The liquid that gets poured in the petrol tank wouldn't clean the jet in many cases. So it could be still partly blocked or faulty, same difference anyways.

Oh right I will have a look into it being blocked too thank you
