Hopefully its something minor, but as a result of poor maintenance by previous owners, my 88 300E failed the idle speed emmisions test but still passed the high speed test. Mechanic determined that engine management computer was running in open loop mode (not managing engine), he fixed that but it still wouldn't pass. Service tech then pulled the valve cover and discovered badly worn cam lobes which was causing engine to emit too much bad stuff at idle speed. Result, major bills. I have heard that if a car fails the high speed test then the catalytic converters could be a potential source of the problem.
My suggestion unless you are a good benz mechanic yourself, take it to a pro for a diagnostic. A friend of mine has an 02 WRX also, sweet car. |

Many point to a worn out cat. One simple trick that might help is to first drive the car on the open road a fair distance - get it good and hot, then take it straight in to the testing facility. Try to be the first one in line. Fully warmed up engines supposedly run a little cleaner. Last edited by Mike Richards; 10-10-2002 at 07:37 AM. |
