Rpm drop when open a/c


First of all, a drop in power when AC turned on, is not uncommon due to the fact that it puts quite a noticeable load on a 4 cyl engine, but in saying that your IAC (idle air control motor) should be compensating for the extra load and adjusting idle to normal when this occurs. Try pulling the IAC off & clean it & port it comes out of real good with throttle body spray cleaner, and re-installl it and see if that helps. As far as steering jerking, take a close look at belt condition as well as tension on belt, as it may need adjustment or belt and/or tensioner replaced.

2004 Kia Sedona keeps stalling


Your problem sounds like you have a bad crankshaft position sensor. You will not get a trouble code (check engine light). This will cause the vehicle to suddenly stall. You cannot change the idle on this vehicle, or any FI modern vehicle contrary to a previous post. It is controlled by the engine management computer by way of an idle air control circuit on the throttle body.

Eng. rpm not dropping when clutching & at idle, rpms go up & down


Here are a couple things to try. The idle surge is a common problem. Ford makes an adjustable plate like the one below. It allows come control over your idle. I made one and it eliminated most of the surging. I think the Ford part is about $30. Can't seem to find the ford part number though. Search online.

http://k-mansparts.com/items/performance/ford-mustang-iac-adjustable-idle-spacer-kit-50-46-f2pz9f939a-detail.htm

Try www.fordfuelinjection.com or other ford sites. Lots of great information.
My 89 seems to roar loud when cold when coming back down to idle and I am sure its the fan clutch. I have also heard the water temp sensor can cause idle problems because the EEC does not know what state the engine is in. (hot/cold, etc)
Hope this helps. I do recommend the adjustable plate though.

Idling problem when ac turned on honda civic lxi 1999


Hi,

To my knowledge (at least in my country), some Honda Civics have a compensator solenoid the pushes on the throttle that adjust the engine's RPM to its standard idling when the A/C compressor is activated. Technically, this solenoid is nothing more but a coil and a plunger. When the compressor runs, the same relay activates this solenoid and pushes the plunger forward increasing the RPM. Pls check/clean/adjust/replace as deemed fit and necessary.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
