losted power
 
i found that my knock senors are bad and are being replaced in about 12 hours,with them being bad will that rob low end torque and horse power?
and also i have a faint low idle miss any ideas what that could be, and does anyone have a factory service manual in a pdf format?

Download these (or one) onto your hard drive. Before they disappear off the web.

You sure the sensors are bad? I just had a similar problem with ses "52" and I did the knock sensor rewire and all is perfect now.

What code is your car throwing?

Followed these directions. http://www.supras.com/06/techcenter/display.php?QID=69 Its really simple. Took me about and hour. The only thing the directions say do that I didnt do was also ground it by the strut. Theres no need to ground both ends, just on by the PCM is fine.

use insulated wire, like rg58. i dont believe network wire is insulated as much as rg58.
