Engine Performance problem
1999 Renault Laguna 4 cyl Two Wheel Drive Manual 107000 miles
My laguna estate 1.9 tdi Disel is having a problem when starting cold.
When I start it it runs with white and then black smoke very lumpy (like it is running on only three pistons plus possible stall time to time plus takes a while to restart after stall.
All runs fine when warmed up also will not rev over 4000 revs cold or hot.
I have changed the glow plugs and manifold and rocker cover gasket problem still there.
Also there is a sound like a bike pump when ticking over when cold which I can not locate then when warmed up goes away and there is some air bubbles in the clear fuel tube top of the engine.
