hi

Q after cam Install and tune ,, after few hours i start my car the idle RPM 1200 - 1300 ,,, tuner said he don't change the idle
and he say check the throttle body wire ??


this is normal ,,, ???

 

Well maye it is stuck, but I would check the ICS (Idle control sensor), sometimes that one gets carbonised and it doesn't function properly. I usualy have to clean that one and the passage 2 times / year. It is above the Idle positioning sensor on driver side of TB.

 

i'll check do you have any pic PREDATOR-Z for ICS ?

 

On the driver side of the TB there is 2 sensors that hook into the harness.
The upper one that looks like a small cylinder is the one. The bottom is the TPS.
It is best to remove the TB to clean it all, but not necessary. Just unplug the harness, unscrew, and remove. Be careful there is a rubber O-ring, you do not want to damage that. Use WD40 or some other mild solvent to clean the sensor itself and the passage in the TB, for that I use Q-tips and some gas.
Once it is all clean just spray a bit of lubricant in the cylinder (just a tiny squirt), wipe off excess and reinstall the sensor.

Should take about 15 min total.

 

nice , I,ll try tonight ,,

thanks

 

My question is what kind of tuner doesnt tune idle?

 

hi PREDATOR-Z

I clean it and same ,, the RPM 1200 -1300
I check my throtall body and it not close completely .. I think this is the problem ,,, how can I fix ?

 

1- Check you idle screw, when blade is in closed mode is it leaning against the screw or not touching?
If touching then see if decreasing screw height will help. If not, check your cable adjustment, maybe it is too tight or cable is sticking. Try removing cable from TB and spray inside of it WD40, puling and releasing the cable from its tube.

Otherwise
Remove the TB, clean it well with carburator cleaner, at the throttle cam etc. Then lube the cam. Sometimes carbon build up on the throat and prevents the blade from closing.

 

ur tuner doesnt have a clue wat is goin on
