Sausage Posted September 2, 2015 Report Share Posted September 2, 2015 What engine is it?I'd do a compression test on the cylinders before spending money on bits for it, you can buy compression testers for about £10 - £20 and they are easy to use, that's cheaper than any garage would charge you to find out if your engine needs money thrown at it.Misfire can be electrical or it can be burnt valves, compression test will help answer which it's likely to be, instead of buying a coil pack and then finding your valves are burnt.

Skezza Posted September 3, 2015 Report Share Posted September 3, 2015 Second FlipFlops really. I would clear everything and then drive it as per and then scan again in a few days. These systems aren't foolproof and are very capable of throwing up errors that don't really exist. Hell, if you let your battery go flat your ECU logs a whole load of faults regarding the airbags and various bits and bobs. They don't always clear themselves either.Clear it, drive it, then see what happens.If your coilpack is on the way out it's a real straightforward job. I'd change the leads and spark plugs too though. Quote Link to comment Share on other sites More sharing options...
Notmylupo Posted September 6, 2015 Author Report Share Posted September 6, 2015 Thanks for the advice, will clear the codes and give it a few days driving.Davyjp Quote Link to comment Share on other sites More sharing options...
Notmylupo Posted September 9, 2015 Author Report Share Posted September 9, 2015 Hi, just to update. Had cleared the codes, drove for a couple of days and rescanned. Misfire codes showed again as did the coolant fault. So I took the advise and changed out coil, leads and plugs this evening. The plugs were in bad nick. My local motor factors didn't have the coolant sensor in stock so it will be done in the next couple of days.Cheers,Davyjp. Quote Link to comment Share on other sites More sharing options...
Skezza Posted September 10, 2015 Report Share Posted September 10, 2015 If your coolant sensor fails, the ECU reverts to a failsafe to correct the bad reading. Might explain if your cars running rich. Quote Link to comment Share on other sites More sharing options...
