Hi im new to this forum n new to vauxhalls..
i recently purchased an x reg astra bertone coupe 2.2 with the z22se engine. Ive noticed a flat spot sometimes when booted... i recently put an ashley system on with no centre silencer and i put a cone filter on but 2 days later my emissions light (diagram of engine) not the car with a spanner in it light (eml) came on constantly.. i searched the net and found cone filters are bad for these engines due to heat soak so replaced it with the standard one...light still on!!. Could heat soak cause the emmisions light? or even the exhaust or cone filter cause it to light ? is it related to the flat spot? could the flat spot be related to a dodgey egr valve? the flat spot only happens after a booting then repressing the acc after changing gear. Im thinking about the egr cheater too.... any advice would be greatful ....if you could keep with it 😃
Must say its a dream to drive other than the little flatspot.
