Have you checked for codes yet? Keep in mind that not all codes will cause the CEL to stay on. To me it almost sounds like a bad connection to the TPS (which 2 of my 3 supra's have had thanks to the lack of that metal clip on the electrical connector). Anyway, check the codes!

Metal CLip????
Neither of my Supras have metal clips on the TPS connector. Here is a pic of what I have. I suppose I can get this clip from the Dealer if it is missing? Or is it inside the connector? I see something metal there. Thanks, Scott

The metal clip (it looks like a paperclip) goes on the outside of the TPS connector. There's a little groove cut in the connector towards the end of it (furthest from the wires) that is slips onto, which helps lock it in place on the TPS. Without it, the connector can vibrate loose giving the ECU intermittent readings from the TPS.

TPS clip
Well I guess I need o get a couple of those. One for each car. Obviously I am missing that clip on both cars if it isn't showing in that pic. I'll stop at the dealer tomorrow and see if they are available. Thanks!

That plug is attached to the wiring harness. So without buying a whole harness, you probably can't get the plug. The best place is probably the junk yard for parts like that. Good luck getting just the clips. On my car I have a few plugs that are broken but never fall off.

Hmmm
Well my plug is fine all I need is the clip. Can anyone post a pic of the connector with the clip on? Thanks, Scott

i just zip tied mine it stays on perfectly has never came loose it could be dirty injectors i doubt its your tps mine does the same thing but only at 2k-2200 2300 and what your describing is a surge check your o2 it might be reading strange giving you a rich/lean condition and check your air flow meter it could also cause this both can happen without throwing codes also because there working within parameters just not at the right time i noticed that my surge became alot less noticable when i unplugged my idle air control
