lexus is250 07 rough idle stalling
2007 is250 awd automatic. 100% oem, no mods.
help me figure out whats wrong without taking it to the dealer. please only reply with relevant information, don't post your own car problems here.
Symptoms: Rough idle and stalls. No check engine light.
Runs good if you give it gas and hold it. sounds like its choking. see video below.
Things i checked and know its not the issue: Spark plugs - bought new Denso sparks. got rid of cylinder 3 misfire, however, car still idles rough and stalls within seconds.
Coil pack - Switched them around to try and get a different symptom, no change.
I did a dry compression test and these are the results i got:
5: 120psi 6: 135psi
3: 160psi 4: 165psi
1: 150psi 2: 160psi
It does seem to burn oil. spark plugs were very dirty, almost looked like burnt oil on them.
I am not sure if the car had the Carbon build up recall thing done, thats next to find out, most likely not.
My next guess is injectors because its running good on WOT(wide open throttle). Not even sure how i would check and see if thats the cause. its getting gas because the fuel line on the intake dripped when i took it off to inspect it. looked fine.
Take a look at the video link below to see what i mean.

I manually cleaned all my intake valves it's not that hard, just make sure they are closed while you do it so no liquid seeps down into the combustion chamber, BUT if u somehow slip up, no biggie, just vacuum it out the combustion chamber lol.

do you think sea foam intake manifold cleaner with the red spray hose thing attached to the can would be useful? I got three cans of it bought a couple years ago and I’ve never used them before.
also, random question but have you ever gotten any recall work done? I saw a couple of recalls mentioning fuel system pipe stuff. I never got them done but now I’m starting to think I should give the provided phone number a phone call one of these days… hope it’s not too late (lol). Anyways…
I hope we both get our issues resolved, cheers

B-12 injector cleaner that's a pour type, not the spray. I haven't gotten any recall work done, I do all my work to my car, I got it at 170k miles tho, now at 200k. I believe the previous owner did get the fuel rail replaced or something bcz the fuel dampers were defective.
