Any help would be greatly appreiciated, i have a 99 v plate 1.4 16v RT megane with 16K on the clock. I purchased this in may 05 and immediatly had to replace one of the plug
(only firing on 3) this resolved the issue and the car ran fine up until 2 days ago. Now it starts straight away but then drops to around 500 RPM, drives badly, vibrates terribly when stationary then stalls when i go to pull off. I've changed the plugs and checked the other
which seem ok as the one i changed earlier was coated in a brown sludge. Renault say it needs to be OBD checked but i'm hoping to avoid this and somebody out there has had the same problem.
