my car is a 190e 2.0 1988 auto. i took of on a 200km journey. it was fine. then we went thru some heavy traffic. i realize that the oil pressure is gradually dropping. so i put it into N. the oil pressure went up from 1.5 to 2. then when i have to go i put it into D and the car stalled in the middle if traffic. after some 30 minutes i get the car started and get it to the side of the road. after waiting on the roadside for 2 hours i get the car started and reach the hotel that was 3km away. <br> i go out that evening again and i realize the oil pressure going down again. this time i stalled but i got it started after 5 minutes a park it on the side. so after an hour i take it to my friends house and got a mechanic to take it away. he changed the ignition coil and the thing beside itt that has two plugs on the it& has siemens/hella on it. he too tried to deliver the car but it stalled. now he says that the fuel filter is choked. could this be the couse? now the car jhas been there for the past 2 days. can anyone tell me what is wrong? my sisters wedding was the next day. so you can understand how i felt. pease help me out. anyone.
