ok i have red alot of post about everyones truck idle going all over the place its so hard to explain but if anyones had the problem lets work together to find the answer if anyone else has fixed this problem anything will help

 

Fixed part of my problem. I just idled it down and the surging stopped. The other problem is the IACV and that will be fixed soon.

 

Ah...what's your problem?

 

ok well mine idles so low some times i will be drivein it it will die so if i idled it down woulnt it make it worse

 

it will idle good one day like a new one and some day it will idle so low it dies

 

please help post pics anything lets make this post big so we can find answer

 

hmmm... my idle problem ended up being A LOT of slack in my timing chain thanks to a broken guide and a shot tensioner and it probably didn't help that the rest of the motor had 296k miles on it

 

keep the ides comin

 

Most of the rough idle problems can be attributed to a dirty mass air flow sensor. This is located in the air intake tube between the air filter box and the throttle body. It is usually held in place by a couple of screws and will have a small wiring harness attached to it. If you unplug the harness and unscrew the two screws you should be able to pull the unit out fairly easy. Use an Electronics Cleaner to spray the VERY small wire inside the bulb without touching it. Let it dry in the sun or whatever, but don't blow on in with compressed air as this could damage it. These things cost about $130 on average, but will last 10 years + if you perform this maintenance on them about once a year. Hope this info helps you

 

your 2 post history shines in that post

 

it is raining here today i will try all ides tomorrow but keep ides coming please

 

it seems to run bad after it has rained

 

MadMan118] 7:32 pm: its most likely carobon build up in the throttle body

 

[MadMan118] 7:28 pm: could be a vacuum leak letting water in

 

MadMan118] 7:31 pm: manifold air pressure

 

algranger] 7:19 pm: o2 sensor maybe

 

[MadMan118] 7:29 pm: or a sensor getting wet

 

Every now and then my truck will idle really low 500 or lower, and then she will die, i can keep her runnin but, when i pop the hood ill most likly find this hose hanging off the intake.

Its the hose that comes off the box next to the air box, its a vac line. I just plug it back in and im good.

 

truthfully, I use to have a similar problem, now that you brought up the fact that it get's worse with the rainy weather

here's my thread on what I found and how I solved it
