Start with the simple things, New plugs sorted me, the same symptoms as you, go from there then????

The engine light came on and flash's light doesn't go out

 

[Fozzy]

Sounds like ignition - plugs, coils and or leads. I’d check them in that order

 

[scoobysub]

First thing . Read the codes then take it from there . The light is staying for a reason ????

 

[Aaronh]

It will be Wednesday hopefully before I can get it on a computer, all I can do now is leave it parked up I'm afraid to drive it!

 

[scoobysub]

Ok wait till Wednesday then you could have a look at the leads and plugs if your handy with the spanners . Start the car and take off 1 coil lead at a time and see does it make any differences with 1 removed it should tick over worse .

So got the car on a computer and its bringing up p0304 misfire cyl 4 and p1235 misfire malfunction so we reckon a coil and 4 plugs?? Had a good poke at the engine and it seems healthy other wise!

Clear the codes, swap the lead on 4. If it comes back cyl 4 again, it's that plug. If misfire comes back on a different cylinder it's that lead.

I'm going to have 4 new plugs put in Saturday should I get leads aswell? What about coil?

 

[Aaronh]

What are the best spark plugs to buy?

 

[Gary sti]

I would start with plugs and do one thing at a time it will also help your trouble shooting have a good look at ones you take out and see condition I think zheiko was selling leads might still have them they where reduced price no harm in changing if giving faults do u have last time plugs changed on service if not might be long over and best to do a full service money well spent
Best of luck with new motor [emoji106]
