Hey

What can be the reason that my IDLE RPMs are at 600 at most. Is there anything that can cause my IDLE stay on 550-600RPMs ?


Thanks

try cleaning your throttle body

 

gnrpatience - Do you have a custom or after market tune installed?

Hello,

Im running the stock filter and stock tune. I cant load my C&L CAI and Tune from brenspeed cause the care went to very low RPMs between 0-500RPMs then its dead.



Thanks

 

What is spec?

 

Hey Nuke,

Waht you mean with spec ?

 

considering that you're having idle issues with multiple tunes, I would start checking PCM inputs (sensors) and outputs (actuators) that can affect idle quality.

are there any other drive ability issues or is it only a low idle concern?
-IDLE rpm only: IAC valve (check motor resistance and movement; BEFORE 2005)
-VARIOUS rpms: MAF sensor (carefully clean and verify correct voltage to airflow numbers- should be a chart for this), Upstream Oxygen sensor (check voltage output- the higher the number, the richer the mixture), Coil packs (voltage to coils, NOT the output!), Spark plugs (check for the correct gap IF not Iridium and burned electrodes)

this is just off the top of my head. if it seems too complicated- take it to a tech. if you're in CA, I could take a look for you.

 

05 and up doesn't have an IAC valve. It's all done by the drive by wire. Mine was idling low...cleaned tb...fixed it right up. Although you may want to unhook the battery for about 30 min to allow the brain to relearn the fuel trims b/c you'll be getting more air. Use carb cleaner and a rag you don't mind sacrificing.

 

you're absolutely right. I forgot which forum I was in. the TB motor would adjust the idle.

 

Im in the process on getting the Cleaners for the MAF Sensor and Throttle Body.


Another issue i find is that when i turn on A/C my RPMs go a little bit more low, they are at 500 RPMs.

Im afraid taking it to the dealership again since the last time i took it for the 30000kms service i start having all this issues.
