i have the skunk2 harness and for some reason when i put the s300 on there the tps doesn't act right and the idle is a little messed up and when i press the gas it revs to 8000 and back down to 1000 and back up. I searched and couldn't find the problem. the stock obd2b ecu works fine no problems at all. does anyone have any solutions would be great to let me know ill post a video of it all later.

 

Ok so some testing here unplugged the tps still same unplugged the iacv and the problem quits but why would that work on my obd2 ecu and not on the obd1 it throws a code but everything works fine so ill run it for now without it plugged in. the tach problem i think i can fix that but. still theres a hesitation till about 15% throttle or so then the motor wants to climb any options on that

 

well the problem after some much needed testing was the tps sensor the s300 wasn't registering it till about 20% so tweaked the tps a little and all good now
