Bluish smoke and idles rough only when cold
I recently purchased a super clean 126,000km , 92, 300D 2.5 Turbo. It blows bluish smoke and idles rough (like a miss) only when cold. All the glow plugs were replaced in Apr/04 by the local MB dealer according to the invoice from the previous owners records. Any ideas where I should look?
Thanks. PD
