Just had a P0302 and P0303 code flag up on ODBII reader after running like a dog when warmed up last few days. I think I may try the plugs and coil packs tomorrow. I was going to try swapping plugs 2&3 for 1&4 to see if it is just plugs as that would read P0301 and P0304? What’s the chances?
id change them as they are relatively cheap . i just bought used coil pack it cost less than £15 and has performed perfectly as new can be a bit pricey
They are very easy to use ..just plug in and scan for codes..worth getting just to diagnose problem even if your not going to be doing the work yourself gives you a heads up of what to expect
Seans Autos I have replaced coil pack and plugs. Engine is running fine now and misfire is gone. Engine light still on tho even after taking Minus off battery for couple hours. Not sure why..
are the codes still showing on the dashboard aswell as the em light... if so what are the codes.....l would try disconnecting battery completely positive and negative overnight
Seans Autos hello! Sorry just picked this up! Yes I can confirm it was that engine code you provided! Thanks very much mate! It’s a small box to the right of the spark plugs ! Top man
