My TPS wire became old and It'll going to cut off the wire, because It idles rough.

So I've been looking for wire connection of TPS but there is only 3 wires of TPS connection.

 

1987 suba GL base ea82 FI (cruise control)

Any advice?

How many wires does your current TPS have?

There are 3 wire, 4 wire, and 5 wire versions around.

not really sure of the wants of the post - think I am missing some detail ??

 

, and don't know why you want to cut a wire because you suspect it is the cause of your bad idle ?

 

there is also a 2 wire TPS on NA mpfi EA82 - I have one !

We have so many threads for the low idle.  Do not mess with you TPS.

 

Make sure you do not have vacuum leaks for starters.

 

Good luck,

Sam
