I've been getting weird idle again like it wanted to die on me and sometimes has .It would idle back and forth between 550 rpm and 900rpm. When I drive it and break the idles go too low to the point that my car wants to turn off unless I rev the engine. I replaced the fuel filter and cleaned the MAF. After doing that I would rev my engine and Everytime I did this the idle went from 900 to 700 or 600rpms. Idk if that solved the problem or if the problem is even fixed. But I would like some info on this idle issue. Also does the fuel filler neck and purge valve contribute to this problem? I have a 1997 land rover discovery series 1 4.0 v8.

 

Post this in the D1 section, it'll get more attention than the "Test Forums" section......
