Engine Performance problem
1993 Ford Thunderbird 6 cyl Two Wheel Drive Automatic
car starts ok idles ok but get rpm around 2000 and car starts to miss and will not rev up. If you put the pedal to the floor the rpms will not top 4000. So onasseleration if you move pedal down then up it seems to start to go and as trans shifts and stays under 2500 rpms you can go as much as 70 to75 for 6 to7 miles then engine lerches and loss of power till you move pedal down and up you can resume your speed. II have disconnected my exhaust pipe left side it begins to miss at 2000 rpm hook it up and with right side disconnected same. So I ruled out left or right converters.I have new wire set plugs, fuel filter, no change.I AM STILL STUMPED? MAF SENSOR MAYBE? HELP!
