High Idle

[Jakecallun20]

Anyone have this problem? I start my engine and it jumps up to 2000 and then sits pretty at 1850..... but when I put it in gear it leaps down to 900-1kish. Is this normal? Anything I could adjust to make it idle lower at around 1100ish (avg idle rate right?) Thanks. Any help is appreciated.

mine idles around 1500 at most in the morning depending on how cold it is i think lol cuz when its really cold outside my car idles around 1500 but when it worms up for a few seconds its good goes down below 1000

I have that. engine is cold. always does that, after a lil bit it goes back down. i think its normal.

Yeah, it's just a substitute for heated catalytic converters (e.g. the kind where there's a heating element integrated into it, but no there's none available and a waste of money to actually get it), since it is only effective when warmed up. Same thing happens to me.

Oh great Im not the nly one who have an idle of 1400 when it's cold outside, Iw as a little bit anxious that the car needs repair, I got my car few weeks ago and it was more warm now it's cold here in canada.

Thanks for the post.

on really cold days the rpm is a bit higher when I start the lara.

I lived in FL for 10 years so far and I feel like I am in summer season the whole time, hahahha.

I didn't know its already cold elsewhere.

Jake,

High idle is normal when an engine is cold but 2000 is a bit high.

Something to check (especially if you're at fairly high mileage and have never done it). Take a look inside the throttle body. Open the butterfly manually and with a flashlight look for a ring of carbon where the butterfly contacts the bore.

If you see carbon, clean it out with (your choice) a toothbrush or Q-Tip and any kind of spray carb or FI cleaner.

What frequently happens is that carbon ring (that should be part of the regular maintenance schedule but isn't) can hold the butterfly open just a bit so the cold idle valve can't do its job.

Your rpm falls back to around 1000 just because the transmission is sucking off enough power to force the rpm lower.

Anyway, check the throttle body, clean it and see if that fixes your problem.

Cheers

Alright, I'll do that thanks. I have never done that before so that will probably help. Mileage is 139151.

cleaning it does help idle.

Alright, Thx. That post said not to use carb cleaner. Thats what I have that will mess something up?
