Hello I found on the site instructions for checking TPS & Idle on the KA24DE & want to know if it is the same on the KA24E? If not what values do I look for on the KA24E TPS ?

THANKS

Is it the same as the DE to check & adjust?

Thanks

I just saw your post, i have an 89 auto hatchback. You will find the adjustment screw at the base of the air intake on the passenger side at the rear. It's not buried like the 91s. On the front of the air intake is the tps just to the side of the throttle body where the butterfly is. Just below that is the connector. Warm up the engine, park it, turn off and disconnect the tps. restart the engine, turn screw clockwise to lower, counter clockwise to raise. when you hit 650 rpms turn off engine, reconnect tps and thats it. I just did this today and my car is at 700 rpm in park. Hope this helps.

To be honest I got the adjustment on another site & it was for the DE. But I know where the position of the TPS should be and that is where it is at .50 volts so the adjustment procedures should be the same. I did exactly what you said at least 10 times before I made this post and when the TPS is set correctly the idle is 1800 RPM even with the screw on the intake turned all the way clockwise it will not go down. The only way to get it to stay at 700 RPM's is to turm the TPS all the way counter clockwise which is at .12 volts (not set to correct voltage .45-.55) Thanks anyway
