is it normal for my rx7 to idle at 3k rpm when i turn it on in the morning after a while it goes down to 1k-1.5k rpm

 

yup, its the Accelerated warmup sequence. should only idle at 3k for like 30 seconds or so.

 

well, i would say.. use the search and read around. not just on the forum, but maybe google.

and depending on how cold the weather is, the AWS(accelerated warm-up system) may take a while longer... especially winter times...

 

what is it supose to idle at once it has warmed up? i also live in miami florida so its actually really hot here

 

idle is 700 +/- 50 If i recall.

 

my Turbo II idles at 2000 but never goes down...

 

^ ~ 750

 

Low Impedance you either have a bridged motor or a problem lol!

 

so if its idles at 1500rpm what should i do?

 

Check your throttle/cruise control cables to see if they are sticking. Something that is easily overlooked before going into more detailed diagnosing.

 

use the screw on top of the throttle body and turn it down to its appropriate idle position

 

i tried that it went down to 1000 and keep going up and down from 1000 to 1500 wont go lower i was told i could be a vacuum leak. also what is the pressure sensor? what does it do.

 

A bouncy idle sounds like the TPS may be out of adjustment.

 

one way my friend always uses to find a vaccuum leak is to turn the engine on and spray carb cleaner and if its revs at any time it sucks up the carb cleaner and that means there's a leak... another think is your gas cap is pressurized so if you unscrew it and you hear no hissing from it, there's most likely a leak

 

oh, if it is a bouncy idle then it is the TPS because thats how i fixed mine... one way to tell with a bouncy idle is to push the end into the TPS to see if that will stop the idle... if when you push anything into the TPS and the erratic idle stops then you know its the Throttle Position Sensor

 

here is the thing tho when i push it all the way down it idles at 700 but soon as i let it go it goes back to 2000 and i fixed the bouncy idle it was as you guys said the TPS.

 

also could the map sensor be an issue in this? the hose connected when i got the car

 

from what i have experienced my whole issue was related to the TPS, now that the bouncy idle is fixed did you use the screw on top of the TB?

 

yea but even when i put it to the lowest its still 1500 rpm
and thats when it starts bouncing

 

My s5 turbs idles at a steady 1500 at start up, but sometimes, say when im starting up for my drive home after work, it can start at 1500, drop to 700 (which is awesome because the Brap Brap sound is very deep) but then lift back to 1500 when she feels the need to, then its a steady idle. its like it has a mind of its own and it never happens regularly, only when she wants to remind me i have to much money.
I have also had a situation that in one particular shopping centre carpark, it doesnt start straight away, i have to coax it and talk lovingly untill she decides that its time to leave..
i heart RE's!! eeehee

 

how big of an issure is 1500-2000 idle

 

what is a pressure sensor? what does it do? and how can i check if mine works. and can that be causing my iddle problem. here are some pictures of the sensor

 

Answered in other thread.

Look in the FUEL AND EMISSION section of the FSM. It outlines a procedure on testing the sensor. Isn't too hard to test.

Doubt it unless the the vacuum hose connecting to the sensor is ripped. I've unplugged my boost sensor (the electrical connector to it) and the car idled the same.

 

yea thats why i was wondering because i disconected it and the idle dint change so i wasant sure if it was working

 

More then likely your cold start cam is sticking, or the coolant lines to the thermowax have been disconnected.

No, NO NO! NEVER, EVER start messing with adjustments like this unless all other problems are eliminated. Trying to fix the idle by adjusting the idle screw (do you really think that such a screw could suddenly be adjusted wrong out of absolutely no where?) is just going to compound the issue until the real problem (described above) is fixed.
