Just installed a scanmaster 2.1 on a stock 86 GN. Have lots of parts waiting to go on but want to know whats these numbers mean first. Wrote down these number while the car was idle. Thanks in advance for the help.

O2 152-300
AF. 08
L8. 38
Bat. 13.2
Int. 128
Bl. 131
Clt. 193
R. 1125-1175
Tps .52
Iac 48
Cc. 172
Nal. 00
 
Thats because the idle tps is WAY WAY too high. Should be .40-.42 at idle NOT .52
 
Yes TPS and IAC are high. Like Dave mentioned that will make it idle high.
With engine warm at idle back the throttle plate screw out until IAC reads between 15-20. Then check TPS number. It should have went down as well. Target is .40-.42. If yours is still above .42, Loosen the top screw on the tps and rock the plug side of the sensor down to further lower the number. I use the screwdriver handle to tap on it. A small amount of movement goes a long way. Go back and check the IAC. You may need to go back and forth between adjustments to nail it down.
 
Also coolant temp is getting in the yellow zone for my liking, and you may need an oxygen sensor if mv's are only going as high as 300.
and wheres the ats?
