Hey guys i feel like after i got my new timing belt installed my idle has been a little low.. when i come to a fast stop it gets to around 400 but doesn't feel like its going to stall.. I will attach 2 photos to show my idle while in park and one while in drive.


My idle while the car is in park looks like 600-700 (1st picture) EDIT*** 06-22-2016 actually 700-750 (AC IS OFF)
and right under the 500 notch while in drive (2nd picture) EDIT*** 06-22-2016 actually 500-550 (AC IS OFF)

working as intended or should I get it checked out?



EDIT*** 06-22-2016

I got my idle checked out by a local reputable shop recommended here on Club Lexus. It turns out both the park idle and in drive idle is within spec.

What I thought was 400RPM was actually 500-550RPM..

Could be a very small vacuum leak, or clogged injectors, or other minor issues.

so it is a little low? is it worth getting checked out?

Sh.t, at stoplights mine likes to go to 300 lol Doesnt bother me IMO, its always best to get something checked so it doesnt lead to something else.

So I got my idle checked out by a reputable local shop recommended here on club lexus.. basically i was told that my idle is within spec and perfectly normal.

My idle was about 750-800, but yeah you could have a small vacuum leak

how about when your car is all warmed up and in drive with the AC off?

Your idle at park is higher than mines definitely

I know this post old, and you probably don't even have that car, but you're reading the rpm gauge incorrectly. It goes in increments of 200 in relations,to the dash marks. Your idle is actually at about 700rpm which is very good, within the factory standard of 600rpm-800rpm range.
