I have a 2000 Contour SE w/ 4 cyl. engine (not sure of size). Never had a problem w/ car until now. Car was running fine when parked. Next morning CEL came on at startup however I didn't notice any problem with operation. Before driving however, I checked all of the usual fluid levels as well as the air filter. No problems. Car was idleing fine. When I pulled out of driveway onto hwy, I noticed a very small amount of sluggishness upon accelerating (really not enough to notice if I hadn't been looking for it). Car accelerated upto 55 mph with no problem. No missing, jerking, jumping, etc.At this point I decided to "Punch it" and see what would happen. Car did begin to increase speed but very slowly (not normal. I pulled over, put into park and revved engine up to what I would consider half "wide open". Everything normal but when I revved higher, engine started "Pulsing" almost seemed like gas was getting to engine in surges. At this point engine would not rev any higher, just sat there and pulsed, actually causing the car to rock in time to the pulses.
I am going to get the error code for the CEL tomorrow, but was just wondering if anyone else has experienced this. I have driven the car for three days in this condition. No problem with starting and driving, just strange acceleration. Thanks
