Abot 2 weeks ago i was cursing @ 85 mph when the cars started to make funny noises and vibebrating. then it died down to 75 and wouldn't go any faster, a few mins later the fit left. 500 miles later (2 days) later it dose it again. but this time is like for 10 mins. well for the 2 weeks it was doing it off and on. About one time a trip. Today on my way to work i was stuck behine some one doing 50 mils slown down and speeding up to 55 and so on. well when i went to kick it down it would do nothing. the rpms didn't rise or the speed. will it did but the ped was to the floor and it took for ever. and to top it off it would hold the speed. i hand to play with the pedle for like 30 miles. Afther work it wasn't so bad it did it's 75 thing when i went up a small hill for a few seconds, then it quits it fit. The computer dosen't tell me anything besids 55. changed plugs 4 days ago oil up, trany up everyhing is up.
Oh by the way it a 95 2L auto with 168750 miles. i love the car but its making me mad

You don't need to go that fast anyways. Keep it at 62.
