I'm having some issues setting up my new throttle body. It's a 68mm OMNI throttle body (obd1 GSR swap in a 2000 civic). I can't get my TPS to .5 volts at closed throttle unless I turn it all the way counter clockwise and turn the throttle stop screw almost all the way out. Once I get it to .5 volts (4.5 WOT) it won't idle. Or, it barely idles at around 200 rpm's.

Has anyone else had this problem? Any suggestions?

 

No one has had this problem?

 

I just got a 70mm OMNI TB for my 01 Prelude and had the same problem. It has an Idle Adjustment screw that I was able to fix this with. Some older posts say that there is not an idle adj screw, so I'm thinking its a new addition to the TB. If your's doesn't have one, maybe you got sent an older model?

My problem now is that after I start driving, when I am coming to a stop as soon as I put the car in neutral the rpms will stay at 2,000 until I come to a complete stop. I just attached a new Omni TPS but I won't have a chance to test drive until next week to see if that fixed it.

 

Is there an idle adjustment screw on your TB? I just purchased a 70mm Omni TB and was able to fix this problem with that.
