Hi guys. I have a Renault clio 1.4 2006. Service light flashed up so I scanned the car and it gave me a P0304. I swapped the coil pack for cylinder 4 with cylinder 1. Drove the car, scanned it and no codes came up (service light stayed on). I scanned it a few days afyer and still no codes came. I left it couple weeks and scanned again today and now it gives a P0300. Can I assume the problem is just the coil pack as the code no longer reads cylinder 4 after swapping? Or should the code have changed to P0301 if it was the coil pack?

Is the engine misfiring? If it isn’t it may be a historic code that needs clearing.

Before assuming, always start by clearing all stored trouble codes, then see what new ones appear. Stored codes could ones from a previously fixed issues, so you clear them first.

When I take off in first gear the car shakes, usually worse with cold engine. It doesn't always do it. The service light on the dash was never there, I've had the car a few years. The OBD 2 scanner wouldn't let me erase the p0304 for some reason, but the p0304 auto disappeared and scanned no code errors for a couple weeks before the p0300 popped up. I'll try erasing the p0300

Do you think I should just go ahead and replace the coil pack that was in cylinder 4, which was the original misfire code. That coil pack is now sitting in cylinder 1 so I'm just a bit confused why the scanner isn't just giving a cylinder 1 misfire (p0301) and instead is giving a random/multi misfire (p0300)?
I guess this is a 16v engine? If so, I’ve always replaced the pencil coils with new ones as a set - Beru have worked well for me.
