hey guys alright my idle problem is back...after 4 days in row of it running just right it decides to do it again...this only happens intermittent, i will be driving idles just fine and when i decide to come to a stop my idle is at 950 and wont go down.....

now...tonight i needed to catch the car twice to test this to make sure what i am testing is right...so it did it again idled to 950 in D and in P it idles to 1400....so i got out of the car and i quickly unplugged the brown plug from the TPS and quickly plugged it back in...and it idled back down and stayed.........parked the car for a few hours drove around for a while to see if it was going to do it again...and guess what it did....i repeated and unplugged the brown plug again and plugged it back in and the idle went back to normal...

now my question: Could this be that i have a faulty TPS?

this is the pic of the brown plug i unplugged and plugged back in....it only works if i unplug and plug back in the brown plug i tried every other sensor and they dont do it...

 

oh yea the car isnt showing any check engine lights or anything at all just doing my head in and causing this problem...

 

not gunna lie, that a clean azz VQ

 

yea my motor is pretty clean...the last owner was an old fella...lol...who took care of the car but after a couple of problems didnt want to fix it...just fix the major oil leak and now this....what do you reckon

 

Tps or even you iacv double check if you have any codes that aren't popping up just have a OBD2 reader hooked up


And Damn that's a clean tb/uim wow

 

im jealous of how clean that TB is lol

Im guess its more to do with your IACV than TPS, but yeah thats the TPS in the pic

 

i dont have any codes come up and why is it that when i unplug the brown plug (while the car is running at high idle) and put it back on it goes back to normal????

 

**oh yea i forgot to mention this aswell**

now when its not on high idle is it normal for when its in P it idles at 900 and in D it drops to 650......

 

and this also..... when in D and im holding the brake the idle stays at 650 if i let go of the brake it will start to like drive itself it will start moving and idle up to 1200 and shift into second gear....is this normal????

 

and i just notice this only happens when the engine is warmed up.....does anyone have any ideas???

 

errr this problem is getting to me....i only just bought the car and i love it to bits but almost makes me want to sell it now and buy another one.... but my determination keeps telling me to just fix it and you will have a nice running car....

 

well i took it for a nice 1 hour drive i notice it was doing it sometimes and sometimes not....now while it was doing it...i played with the plugs on the tps...i didnt unplug them but i wiggled them...and the idle went back to normal......now am i getting closer to finding my problem????

 

IACV not closing. Could be going out.

 

I would have to agree. Mine went out in my i30 about a month back and I had almost the exact same symptoms. After I replaced the IACV the car went back to normal idle. It took me forever to figure out because it wasn't throwing up any codes.
