just got my injen on sounds greattttt!
but
my cel came on and when i stop the rpms will go up and down a little.anyone know what its doin or what i should do?
helpp plzzzzzzzzzzzzz

 

search #1 as this has been dicussed before but since im getting laid tonight, ill help ya out

Cel is 99% lean code, jsut get HP tuners and clear it and delete it for good. as for the RPMS, mine does that sometimes if im cruising down in 5th and shift to N around 10-20mph. my rpms will drop to 500 or so then kick back up to idle. Been doing that on me for 47k miles and its really nothing to worry about.

 

can the dealer do anything about it cuz i dont wanna deal with hpt

 

I've heard of a few cars with funny idle, but it shouldn't directly be the injen. I didn't have a problem with it at all in 5,000 miles. I'm sure disabling the code will help, but surely there is some other underlying cause since not all injen installs are causing this and a lot of people have to get reflashed to fix idle issues.

 

i unpluged the battery for about 5 mins cel went off and everything is runing fun =]

 

brad, there was a TSB about erratic idle a while back...also, some people say to remove the NEGATIVE battery terminal before installing an intake so the PCM will relearn the new A/F curves. I just got my car back and put my intake back on, but i think im gonna have to take the car back in cuz its still acting a little funny...

 

haha good timing lol

 

Does this also affect the 05 2.2L's?

 

here's a link to the thread that fr33k posted...it has the list in it.

is this bouncing under acceleration? or just idle? if it's bouncing when idle, then it can be fixed with a reflash or stage 2. if it's under acceleration, then it might be because you have your maf sensor backwards.


those are my two cents.

 

this is straight from the list:

#06-06-04-039 LSJ Fluctuating, Unstable or Incorrect Engine Idle (Reprogram ECM) - (Aug 10, 2006)

thats what I was talking about.

 

so how do i fix it

 

if its still doing it, you may have to take the car back to the dealer and have the PCM reflashed. Even though you dont have a stage 1 or 2, they will still reflash the PCM because of the erratic idle

 

make sure everything is nice and tight and unhook your bat.... thats all you can do at home.... like it says above if it keeps on your gona have to bite the bullet and go to the stealership

 

i would try this first. but then if it comes back.. just take it to the dealer. they cant/wont void your warranty for an intake.

p.s. autozone will read the code for you for free.

 

make sure the mas air is tight. don't kung fu grip it. you will break it.
make sure all the clamps are tight as well, on the tb, and the pcv/breather
