Thanks for all the input remember that the car is running rich at idle only not when its been accelerated.

Hello Gang, I have a 2001 Land Rover Discovery 2 gas engine with about 140k miles I took it to get it tested for emission ( smog ) its a requirement here in California to renew registration and it failed the guy said its running too rich at idle. Here is the test result maybe someone can recognize what could be wrong. GAS Reading HC..........PPM: 394 ( he said it needs to be 70 ) CO.............%: 4.60 ( he said it needs to be .5 ) CO2...........%: 8.2 O2.............%: 6.4 P.E.F ............: 0.469 If anyone had any idea what could be wrong please let me know your help will be greatly appreciated. Thanks Sam
