ALOHA!!!
Ok so every time i start up my truck in the morning, i put it in neutral and press the (start .... clutch button) not holding in the clutch and truck starts up with a high idle!!, either way, it still starts up with a high idle over 2000 RPM. when i press in the clutch and put it in gear and start to go, the RPM idle drops lower, and gets softer. so it seems like every time im in neutral it give the high idle problem. but sometimes during the day is starts up with a mild idle i would say about 1500 RPM. what could possibly be the problem??
Check engine light is on and i read them and it was code 24 intake air sensor, and 52 knock sensor. could it be the intake air sensor???/ PLEASE HELP i would gladly appreciate it

 

fix the codes first, then worry about idle......

 

moanamilla, please refer back to the other thread u started on this subject, thats why they keep combining them into one.... as many people have said fix the codes first before trying to fix the idle. if there is a check engine light trying to adjust the idle wont do u any good.
