Idle problem...please help
Idle problem...please help
I went away for 1 month and after i came back and start my lovely 2003 TLS, it took about 15 min to start after it start the rpm go up and down from 1000 to 2000 and the engine came on and after a few min. all light are came on like VCR, tracktion control and engine check, i asked a menber he told me the idle air control need to be clean, i took to Tire plus and they clean it for me, it didn't worked and they told me i need to replace trottle body too. please help, i need you guys idea, thank you..
it took a lot of battery to get it started-15 minutes!!! yikes-
that drains battery plus its been sitting so it was already weak
Low voltage causes many false codes
first charge the battery on a battery charger
then you need to reset the ecu by pulling the CLOCK fuse on passenger end of dash
No need to remove battery neg cable as that requires input of radio security code afterwards,,clock fuse is secret backup power to the ecu and forces a reset
you may have moisture in the fuel, add seafoam to tank at 2 oz per gallon of fuel
and drive it
if that doesnt fix it, remove TB and clean IACV on bottem of TB
need to know exactly what the shop did-

My 2 cents take it out and get on it for a little while and see if the idle cleans it self up. Sounds like the IACV is sticking from sitting. If it doesnt after a 15-20 min drive take the IACV off the bottom of the TB and clean it. Dont disconnect the battery. Pull the CLock Backup fuse on the passenger side dash fuse panel, it will reset the ECU (note that disconnecting the battery or resetting the ECU you should do a idle learn procedure as stated in your manual)

did you get the battery charged and taking it for a good drive today.. with seafoam in the gas?
2 oz per gallon of fuel for max cleaning strength to get rid of gummed up whatever in your system
ck tire pressures- sitting a month and ambient temp changes will affect them greatly

I have had this same issue happen to me twice and adding more (different) gas cured it. I chalked it up to a bad batch of gas. Since your car was sitting for a while, I'm guessing the gas is bad or contains water that go in somehow. (keep in mind water sits on the bottom of the tank since gas is lighter than water)
Fill the tank with high-test and see what happens.
Good luck !

I did evertihing you guys said but it didn't work, I clean the IACV and TB, but the problem wasn't gone but after that i filled up the tank with seafoam, let see what happen, thank you for all comment. And i will post it.
how much seafoam to gas did you use?
for problems and cleaning dose its 2 oz per gal of fuel
it may take a few tanks of treated gas to get rid of the prob--
someone the other day idle prob and good gas treatment and drive cleared it
