hi, i have a 2005 dodge ram 1500 5.7L, and in the morning or after i get off work my truck will idle way to low and cut off whenever i come to a stop or put it in reverse, even when the truck is good and warmed up it will idle pretty low when i stop, i took it to a mechanic and he thought it was the fuel system so he cleaned it all out, and of course he said it didnt do the trouble when he drove it, well its still doing it and it so frustrating, can anybody help?...oh yeah it has 64,000 miles on it and no engine lights come on when it does it either....thanks

 

Have you cleaned the TB? Also maybe the TPS? Just thinking out loud.

 

Maybe check or replace the Throttle Positioning Sensor??

 

From other threads I have read, check your egr valve.

 

I feel your pain... I have the same issue on my 06 mega cab I have 65K on mine. I have have this issue since about 20K. I have had a few professionals try to seek it out with no prevail.

 

check trans fluid also

 

Had the same problem with my Jeep Grand Cherokee. Check the Idle Air Control Valve. The stupid part gave me nightmares in the daytime. Would start right up, drive down the street, then the idle would drop, accelerator would not respond, then suddenly lunge forward in a split second. Also, it would turn over but never quite engage, at times. I removed the IACV, cleaned it and Voila! The darn thing was cured. Well, at least until the next time it died on me...that was a different problem altogether. By the way, it never threw any codes when this would occur...give it a try.

 

its at the shop right now hopefully it will get fixed this time

 

Let us know what you find out

 

finally got it fixed! the transmission fluid had a leak and was 3qts low, would of checked that but i thought that where i got my oil changed at would have checked those levels but i was wrong..but fixed nonetheless
