Hi, has anyone experienced this problem, my 02 paty wants to keep going when I brake. rpm stays at about 1000rpm and if I put it into neutral it races to about 2000 rpm drops to about 1750 for half a second then back to 2000 . if I punch the gas pedal it will settle down to normal. This is really messing with my fuel economy. I guess I have to play that sensor game but which one first?? Thanks in advance for any hep on this one Chris
