Hi wonder if anyone can help. I have a 03 206 1.4 petrol. It started to run rough a few days ago missing, sounding like it was only running on 3 or even 2 cyliders. I have replaced the spark plugs.& coil pack. Started fine run lovely. Went five miles down the road, stopped did a bit of work came out & its doing it again. Has anyone come across this before & could shed some light on what to do next. Cheers
Going by you description it sounds like you have a single coil pack. These are usually a wasted spark system (i.e. one coil fires two spark plugs) so missing on two cylinders is quite possible. Have you checked the wiring to the coil pack.
I tried to look up your car and I think 2003 was the year Peugeot updated the car. The later full multiplex version of the 206 appears to have individual coils on each spark plug. I couldn't find much info on the ignition system for the earlier version 1.4l engine. Do you know your exact engine designation? If you register with Peugeot Service Box entering your VIN should give you a few limited details. Peugeot now charge for a full report.
Have bought new coilpack still missing. Someone has put a snapon on it and came up with code P1327, they seem to think ECU. If i buy a second hand one from flea-bay how would i get it recoded to my vehicle. Thanks Reg.
Before you change the ECU I suggest you check the three connectors on the ECU. Water can get into these connectors.
I think the Snapon OBD tester usually gives a description as well as the fault number so the diagnosis of a faulty ECU may be correct but P1327 could mean an intermittent crankshaft position sensor.
No got Bosch plugs & as far as i know no modifications that i know of. Cheers Reg.
