Whenever I turn my fan on my Car is alright for a bit... but if say I chagne the settings around a bit it throws a check engine light once in a while, same with the AC except with the ac my car's idle goes alot lower than what it normaly is... Say if im parked at a light with it on after driving a while... instead of say something like 800 at idle it goes down to like 300 idle or so... car also gives a pitch sound when driving not sure if thats something wrong there but when the ac is on and driving the car sounds different... Car also sometimes when messing with the ac and fan also my car will almost bog out and die if sitting stationary then my car will go check engine like and my fan and ac will turn itself off and wont turn on again unless i turn the car off and on again... any idea's?

 

my idle goes REAL low after i turn ac on. then sometimes the idle it just bounces up and down. dunno my car is weird

 

my first gear would bog w/ ac on

don't think i've had a check engine light when it happen tho.

the ac plug fell out haha shoulda checked that myself haha

i recently had the same problem, drove me crazy. literally.

first check your code.

i got money on your tps being shot.

 

i might sound stupid, whats tps???

 

throttle position sensor, its located on the back of your throttle body (the housing where your intake tube mounts into). it looks like this = http://www.jhpusa.com/store/pc...=2439

i dont recommend buying this aftermarket product, get OEM, and i dont recommend changing it out yet. check your code first, like i said. do you know how to check for codes?

 

sry i dont im a noob n not that experienced on workin with engines but im not scared to try . i dont even get a check engine light

 

my bad i thought i was talking to the OP. but anyway, in your case, i never got a CEL either. you still might have a code 7 (tps). to check for codes... read this link carefully and follow instructions. https://honda-tech.com/zerothread?id=978933

 

i checked the codes and i get 1 long flash and 7 short flashes and 4 abs short flashes. so could it be da speed sensor??? oh i got jdm ecu btw

17 VSS - speed sensor

 

i doubt the speed sensor can cause the idle problem??? could it??
