today while i was driving i was bombarded with these symptoms.. cant rev over 4000 rpm's car wont stay running. i will hit the throttle and nothing then out of nowhere power would sputter back in. car was barley able to maintain speeds of 35 to 40 mph.. you can put it to the floor and nothing happens... a/f gauge would not read also. just wondering if anyone else has had this problem before. I just thought the tps sensor would be a good place to start. any feedback would be appreciated. thanks....
