lol, getting there

 

Why not use the idle screw on the actual TB, and then use the IACV to fine tune it if at all needed?
This is how Ive adjusted mine in the past. Just using the IACV adjustment didnt work too well for me.

 

Where is the one on the TB? I've never noticed it...unless I'm blind.

 

Asides from the exhaust rattle, allthough I geuss I could see that to, all of your problems were related to the minor vacuum leak your old pcv was causing..........

 

My favorite reason: Because the fsm says not to.

 

I hope you weren't taking a subtle stab at me. If you were, I didn't know such a screw existed. Please enlighten me as to where it is.

 

which TB screw are we talking about?

 

i think they all mean the tps adjustment, there ARE no idle asjustment screws on throttle bodies of 4th gens. post a pic if u dare!

 

That's what I was starting to think because someone mentioned that it makes the throttle better and I know that the TPS does that as I just replaced mine a few months ago. You could do it that way...but I dunno...I find the IACV screw much easier to access and to regulate. But that's just me.

 

You mean the two screws that hold the TPS in place? Pics?

 

Nah...Andruxa was just saying to post pics of the TB screw if there is one because he doesn't believe there is and neither do I. If they are refering to the TPS, then yes. It has the two connectors on top and two little screws...which when you loosen you can "spin" the actual sensor...therefore changing the setting. A symptom of a bad TPS or an unadjusted one is stuff that I experienced when mine died...I had the following:

Gears would "bang" as if the tranny was bad.
I couldn't rev the engine past 3k rpm...otherwise it would cut off and go back down to 1k.

When it started happening...I thought my tranny was toast. It was just a $80 sensor.

 

yeah thats exactly what i think....

 

oil catch can is NOT a must to run a s/c but its a MUST if you are concerned with leakage. some members have had leaking blowers and the oil got into TB from what ive read.

as for the slammed look, well the ride in the city is better since the speeds are much lower, your average bump doesnt bounce you around all that much. on highway the handling is top notch but the car is just too low and 35 profile tires dont help the ride quality all that much. i agree that on the highway it CAN be a smooth ride given proper smooth roads but if your doing 85mph and hit a pothole or uneven surface, either you blow a tire/bend your rim or you bounce off the ground and catch air. both of these can easily be avoided in the city @ 35mph

 

I think i'll just leave the TPS alone, Ilusha. Don't wanna mess with it.

 

lol! Ti tozhe slavyan? Ruskiy or ukrainets? Moya sestra zhive v Philadelphiyi.

And I see you're a computer techie, as am I. Nice.

Its actually the stop screw, but its used to adjust the idle.
This is how Ive always been told to adjust the idle,
I can post a pic this evening when I get home. I have me A32 TB in my shed.Im running a PF TB now so the stop screw is a bit different but does the exact same thing.

 

got to agree a few months ago i made a 1008 miles trip and car felt great and it only took like 2 3/4 tanks even when i step on the gas most of the time

 

Flava_24/7, it's like a stopper screw for the throttle plate?

 

Werd. Things I've changed for the heck of it with no noticeable difference:
O2 sensors
fuel filter
knock sensor
pcv
cat
Water Wetter

so the theory of replacing o2 sensors Without any CEL lights on to improve MPG is not true huh, good i always knew to wait for the CEL to replace any sensors

 

he-he-he ROFL

 

Lolz, a little paranoid 'eh? I quoted the poster not you, and that was not meant as a stab of any type either

That screw (on the left in that photo) for the throttle stop is calibrated from the factory and allthough it will effect the idle it is not recommended to do so for several reason's, throwing the tps out of the range of proper adjustment is one, same for the iac in theory anyways, and possibly some other ones that I can't explain, I'm tired.

But anyways, since there is a lot of talk and questions about idle adjustment in this thread, ftr...........

 

And don't skip the preperation part to "make sure the following parts are in good order", that is KEY, especially #9 as someone else mentioned in this thread about 'before tossing money at it', or maybe that was a different thread, whatever

 

60k city miles huh. It just means you haven't used the axles and tires as much. I couldn't imagine not taking my Max on longer trips, it drives so smoothly and the power at speed is great. I guess you just have a show car. Eh, to each his or her own. 172k miles here. Seems to be working fine, although I don't have it dropped or 18" wheels.

 

I thought so too, till I drove a friend's Scion tC. Easily accelerates in 5th gear, whereas my 5th gear stinks. Funny, cuz sticker for my car's about the same as my friend's. LOL. Times have changed.
