I was driving my car down the road when all of a sudden i start to loose power gradually. I stepped on the throttle and put it to the floor and the only thing that happened was my RPM's went up high and the speed went up very slowly. It felt like a massive lack of power. I have not changed the fuel filter yet so that is where I am going to start. However for about a year or two I have had the dreaded DMF noise going on. Unfortunately the geniuses at my local VW dealership changed my transmission several years ago and it has not been the same sense. About a month ago I disconnected the air intake and put it back on without a clamp, irresponsible I know, in my defense I didi not have screw on clamps just the pain in the ass OEM ones. I inspected to see if the intake tube had come loose but I did not, and no CEL came on. I drove the car again and it is better. Any suggestions?
