Everytime I start my truck it revs to about 3k on it's own. After a few minute or so it'll die down and choke and then run normal. If I try to drive it it will speed up on it's own (to about 20-25mph). Today we put seafoam and throttle body cleaner on it hoping that would help. It runs better but it still has the starting problem. Any ideas on what this problem could be??

Thanks

 

i think its the owner

 

sounds like a sticky throttle body..

 

but we cleaned it all today with throttle body cleaner... how else would i fix this??

 

did u clean you Idle air control sensor also that could cause the high idle and being a roufgh idle. prob also clean the Mass air flow sensor wile ur at it also. never hurts unless u brake it.

 

Hwo cold is it out there?

 

cold?? haha it's texas around 70... Where is the idle air controller?

 

idk about the speeding up on its own.. haha i would have to agree on its owner


butttt, about the truck idling high.. i have the same problem but slightly different
i know for my 99, maybe your 00 theres a TSB out about that, it requires the CPU gets flashed i believe, i have the print out in my truck

 

that too, throttle position sensor, PCV valve can cause funky things to happen..

 

Sure it isn't normal? How long does it do it? Its been around 30 degrees here but Everytime I start my truck it goes to about 2,800 for a couple seconds then down to 2k for maybe 5 secs then under 1,500k

 

no it's goes up to about 3k then stays there for about 2-3 mins then calms down and chokes then runs normal... anyone got a pic of the throttle position sensor and the pcv valve

 

Soprry I just seen were you said "a few minutes...."

 

what engine do u have?

i can go take a pic and show u exactly where it is if you have the OHV... i know the PCV valve on the SOHC is a pain in the *** to get to..

 

yeah i've got the ohv

 

alright gimme a few

 

even if it isnt bad, its not a bad thing to replace at only like $2-5

if you take it out, and shake it, you should hear something in it rattling around, thats a good thing haha



...sorry about the long delay, my computer hates me today








may not be the problem. probably wont cause it to idle like that now that i think about it, go to the shop or dealer maybe, and see of that TSB pertains to your truck..

 

the Idle air control sensor u can see in his pics. the 1's and 2nd pic it is the shiny cylinder looking thing with the wires going to it i belive. it cna get some carbon in it and u can spray it down and use a tooth brush

 

stupid *** engines. so many things that can cause one problem lol
