I just purchased a 1993 190e with the 2.6 and automatic trans. I paid very little for the car it has 158K on it. Above 1500 rpms it runs great and pulls good, under that say at idle and when you take off from a stop it is very rough and sometimes cuts in and out. The car has been sitting since february with a full tank of gas i've only put on maybe 100 miles. I have put some fuel revitalizer and cleaner in the tank and ran maybe 10 miles, i have also replaced the spark plugs, waiting on the wires to arrive. Just wondering if there is anything else I can do, any problem areas on these cars? Thank you
