I too have a laguna with the IDE engine, don't worry about a lumpy tickover, I changed the oil to Amsoil European formula (AMSOIL Performance Oils Ltd) and things got marginly better my motor has done 123k miles and still gives 30+ mpg and will do a ton easily. Beware random faults coming up such as "fuel injection fault" "ESP fault" and the car going into "limp" mode (10mph) cherck the loom in the engine bay especially the throttle body plug. The lumpy idle comes and goes depending on the temperature outside I think you can fit a resistor across the temp guage sensor but am no sure (it is supposed to fool the ECU into thinking it is colder and so increases the revs

ps if all the above scares you get rid
