truck idling high

hey I am lucky because I can walk to a parts store, but I took two off, and went to advance, and they matched and cut two for me.

 

Yea. I might just buy a spool or something for the bigger hose then get the smaller ones cut for me

 

I have been driving my truck a little after being back home and it seems that my high idle when cold is 1700-2000 then it will settle to about 1200 when warm but in park it will drop to the 800-900 range but as soon as I put it in drive it bounces back up to the 1200 range. I am going to do my vacuum hoses this weekend but any other thoughts and what could cause this disparity in the park and drive idle levels?

 

your tranny will load the engine in gear. If your low idle is too low in park then when you select a gear it will bog the engine down

 

hey, I can't remember how much stuff you have done already, but last week on top of the other things I have done to mine, I replaced the TPS and put on 2 new o2 sensors. while I did not throw a code, I will tell you that they were the worst sensors I have come across, and my idle and gas mileage, has improved. when I got my truck last fall, it was like yours, and now its 1200 cold and 900 warm, and very smooth and quiet.
I had posted a pic of the sensors , can repost if you want to see them,
but it makes a difference.
and next month new coils, and I will be happy.
