ok here is the deal. i used a wiring diagram from celicasupra.com to do the install. i followed all of the directions to the "T". when the unit is set up and i turn the car on it surges at idle! it just rises....studders...falls...rises studders falls and dies. when i unhook the af signal wires from the safc and reconnect the stock wires it runs perfect.

any ideas? do these work with my year "83" supra? am i an idiot and did i hook it up wrong? PLEASE HELP!

ahhh...i figured it out! the damn install diagram from celica supras was wrong! it says the ecu afm signal wire is plug "Vc" when in reality it is plug "vs". it works great now!

i hope this helps some one else.
