Idling Help!

Hey im new to mbworld,I just had a quick question for you. I have a 1996 E-320 it has 158K its been a good car unfortunatly I started to have a major problem i believe. When I put the car in Park or stop the motor will start to idle like crazy it will go from 0-2rpm non stop till i change gears in then it will continue to do it but not as much. This happends on and off. I would really appreciate it if you can help me out I would like to fix it my self if its not a major problem. please help me I dont want my car to screw up. Thank you.

do you have check engine light on?
if not i'm guessing something to do with the idle controller valve.

the check engine light is on. I hooked up the ODB3 it reads "MAF or VAF A CKT range/perf" ( P0101) could it be that the maf sensor is just dirty?

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
When they

get dirty or a bit out of range the codes are usually the fuel trim codes on both banks of cylinders.The p0101 circuit range code is most likely a bad maf circuit so firdt make sure it is plugged in and that the wires are in good shape if they are then a new maf (not ebay) from autohausaz,com will solve the problem.
ohlord
always a good idea to check all other systems at the same time,clear the code and see what codes return.Check all the spark plug connectors to be sure you have no misfires.
