well this is the second time that this has happened, the first time was last week, i was waiting to pull up to a gas pump and my idle dropped down to around 500 rpm and it started getting shaky like it was choking out but went away after about 10-15 seconds.

today it happened again, i was sitting at a light waiting to turn and it did it again, but i just gunned the hell out of it and made my turn and it went away after about the same amount of time.

what could cause this?

 

If you can pinpoint the cause let me know! Mine is doing the same and have no clue about what's making it do that!!!

 

clean the tps....what do your trucks normally idle at? mine idles at 500 and is rock steady

 

dont you mean IAC.

 

whichever one works! I used to have to clean the tps on my s-10 when the idle got funky....so the acronym stuck...lol

 

it idles around 700-750 normally

 

Mine idles a 700rpms. I have checked the throttle body and it was clean, the tps, iac whatever it's called and everything was ok. I'm going to try autolites 3923 to see if it makes a difference....

 

guess it's time to check under the hood to see what my idle SHOULD be....then decide if I need to do anythign about it....

 

What yall are talkin about is when you are idleing, you can feel each cylinder firing, and it is kinda shaking the entire truck? My truck is idleing at about 700-750 rpm's but it does go down to 500 on cold mornings. It also has a tick, that sounds like a lifter tick, that you can barely hear, but it comes and goes. Before i hit that deer, my 3.7 was ticking like a diesel.

 

well it feels like its almost choking out and dying, i get scared so i give it gas. dont wanna be stuck in the middle of the road
