I have a 2014 peugeot partner tepee petrol (1.6L engine). I drove it on a 10 minute journey yesterday and the engine misfired once. I didn't think it was something to worry about at first but then went on a 40 minute journey down the motorway later the same day. It happened again a couple of times which started to worry me, and then when I was about to come off the motorway, it did it again and this time the check engine light came on. I pulled over and the fan on the car was working really hard after I turned the engine off for a while, but the temperature gauge on the dashboard didn't say it was overheating (it was slightly higher than normal but it was also a hot day). I had recently had to top the oil up because the oil light had come on, but there had been no obvious oil leak anywhere so I had just topped it up and continued to run it, assuming that it was just burning a bit of oil. I had to get it back to my house (20 miles) so I drove very slowly a non-motorway route, using the accelerator as little as possible. I pulled over a couple of times to turn the engine off briefly and the second time, the check engine light didn't come back on. I continued to drive slowly and got home with no more misfires or problems and the fan was quiet when I stopped. I'm going to take it to a garage later today but want to have as much information as possible before I go to avoid getting ripped off as I'm quite new to the area (Gloucester) and so will be risking going to a new garage for the first time. I don't like to go with no information at all so if this sounds like a particular problem it would be great to know in advance, or at least have an idea of some of the most likely causes.

Ok gents, I have an 02 town car with 123k miles, Im the 2nd owner and have 100% of all service records back to the bill of sale. The only thing on it that isnt from Ford are the NGK plugs and ENA coils I just put on it to try and eliminate this issue. Last week I started getting a VERY noticeable miss while driving, bad enough my service engine light was flashing occasionally. The plugs and coils had never been replaced so I figured that was most likely it. The car ran perfectly for 1 day afterwards and I thought the issue was done, then the next day I had a couple misses when cold but cleared up with it warmed up, now today I have misses again all across the temp range and in all gears. It worse when the car is under more of a load, like going up hill, or when I have to slow down and then accelerate again but I can tell the car is still in a higher gear and the rpms are low. I have no CEL/SEL codes right now but I did do a Mode 6 scan and came up with some issues but I have no idea the meaning or translation of them since they are in hexdec. Ill include them with what little info I have about them in case someone has the ability to translate them. As for any other maintenance/parts in relation to the fuel system: fuel pump and filter replaced 15k miles ago with ford parts by ford. Does the ECU need to be reset after new coils are installed? Could it be that simple? Any suggestions would be appreciated Mode 6 info: TID: 2B CID: 00 MIN: 0x8A00 Val: 0x00 Max: - Phase 4 Vapor generation maximum absolute pressure rise and max threshold TID: 2A CID: 00 Min 0x8700 Val: 0x00 Max: - Phase 4 Vapor generation maximum change in pressure and max threshold TID: 55 CID: 00 Min - Val: 0x2F1 Max: 0x28F Highest emission-threshold misfire and emission threshold misfire rate (updated when DTC set or clears) TID: 56 CID: 00 Min - Val: 0x4FFF Max: 0xFA0 Cylinder events tested and number of events required for a 1000 rev test
