#32: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Wed Mar 04, 2015 11:13 am ---- New coil pack and Bosch plugs seems to be perfect now - sweet if now a little poorer again !!!!!!!!!!!!!!!!
#33: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Wed Mar 04, 2015 3:18 pm ---- oh and it had NGK plugs in it - not sure they are that bad but now has proper Bosch ones

Lumpy idle returned this morning big time!
Dash came up with the 'catalytic converter fault' - engine light came on - fault reader came up with P0300 Random multiple cylinder misfire detected - few minutes car warmed up and drove fine - still with the engine light on. Started the car after 30 minutes or so and now the dashboard comes up with 'Antipollution fault' - still with the reader giveing me the same P0300 multiple missfire code
What the bloody hells going on - I know its a French car but what !?!?!?!?!?!
I put a new coil pack in it yesterday as well as 4 new Bosch plugs - took it home drove perfectly and gaveit a wash
Any ideas?

#36: Re: 206 GTi lumpy idle Author: Addaz, Location: SuffolkPosted: Fri Mar 06, 2015 1:10 pm ---- Its injection so no
Have you checked the compression? Have you checked the injectors?
#37: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Fri Mar 06, 2015 1:23 pm ---- Havent checked either - wouldnt either show up a fault code??
#38: Re: 206 GTi lumpy idle Author: Addaz, Location: SuffolkPosted: Sat Mar 07, 2015 6:05 am ---- Yes, multiple misfire
#39: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Sat Mar 07, 2015 6:31 am ---- Right have used a better code reader and it threw up multiple errors and misfire cyliner two so as its only done this since i replaced the coilpack i swaped it for anotger one from eurocar parts cleaned all the connections etc wd40 spray and cleaned all the contacts on the ecu as someone suggested that
seems to.be running ok - the injector cycle came up.all ok so maybe dodgy coil pack??

Starts and runs fine but still a lumpy shakey idle at cold start up - once at 70c + it runs sweet and runs very nicely - mpg is good and getting better 24 - 25 mpg in really bad traffic in SW London so its not the lambdas (didnt show any fault on them anyway)
Slightly fed up with my French car now - shame as it really goes well otherwise
#41: Re: 206 GTi lumpy idle Author: Addaz, Location: SuffolkPosted: Sat Mar 07, 2015 2:13 pm ---- What are the resistance readings across the injectors?
Are the plugs tight? What are the compression readings?
What are the MAP readings on idle?
#42: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Sat Mar 07, 2015 2:19 pm ---- Need to do a compression test
#43: Re: 206 GTi lumpy idle Author: johnpidge, Posted: Sat Mar 07, 2015 2:21 pm ---- I will.check the other readings what should the Map readings be??
#44: Re: 206 GTi lumpy idle Author: Addaz, Location: SuffolkPosted: Sun Mar 08, 2015 5:30 am ---- Around 300 to 400 on idle
