Everytime I have set my timing it is done wit the TPS unplugged. You are really supposed to make sure that the idle speed is around 800 when setting the timing. You can adjust the idle screw if necessary. There have been people who cannot lower the idle speed enough with the screw. You cannot set the base timing with the idle speed high.
On a side note
**Mostly the main cause of the idle issue is a dirty IAC valve.**
It's tucked under the intake manifold near the fire wall. Very hard to get at and expensive if you take it to a shop to get it fixed. But it doesn't need to be replaced, you can fix your nasty idle issues for less then $10! Here's how...
Get a bottle of Intake cleaner, not carb cleaner, intake cleaner.
See this hose:
The bigger one on the right goes from your intake to the IAC valve. If you pull it off while your car is running it will die after a second or two. When your car is off, pull the hose off but leave it still on the nipple enough to seal. Go start your car and then come and using one hand pull the hose off and with the other hand keep your idle up by opening the throttle. With your now free hand get the bottle of intake cleaner and spray some of it into the IAC tube. The car will stumble but make sure to keep it from dieing or you will have to put the tube back on and start the process all over again. Repeat this process several times,use about half the can. Re-install the tube and take the car for a drive! I drive for about 20 minutes and everything should fine.Do this and you should have no idle problems.

Awesome, Thank you so much. I knew you'll have options.
Do you suggest any brand of cleaner in particular?

To adjust the tps on a ka24de, move the tps so the signal is returning .5 volts while closed and 3.5-5v wide open. Use multimeter on signal wire while key is on. Back probe the connector while its plugged into the tps.
Set it to .5v closed, if it dose not go to 3.5-5v when opened then it needs to be replaced.

Can any of you, 240 Sickness or Aero-K guys help me do this. I rather pay someone who knows how to do it. I don't know how to set the timing. I neither have Voltage meter/multimeter or know how to use one. The whole cleaning the IAC valve helped to bring the idling from 500 RPMS to 1500 RPMS without me trying to adjust anything else LOL! So I supposed that is a good thing but my idling is still not normal and when my TPS went bad, I just installed the new one at whatever position it fell on. Please help someone. Thanx!
Id tell you to bring the car to county line tomorrow but my tools are at the shop. If you want you can come by the shop one day after 5 and I can take a look at it, pm me.
