Engine Performance problem
2000 Renault Megane 4 cyl Two Wheel Drive Manual 240000 miles
Engine starts fine, idle is a little high. After 10-15 mins idle speed becomes erratic, continuously changing from 700 rpm to 1800 rpm and dropping again repeating every couple of seconds - a bit like challenging the next door car!
The problem is intermittent - soemtimies happens, sometimes doesn't.
Engine perfromance is fine.
It has been doing this intermittently for a year or two the Renault people report that there is no fault code shown on their computer.
All filters, plugs, cam belt etc have been changed at recommended periods
have the same problem?
