Solving Idle Problems
I might get more requests about idle issues than any other topic. I think part of the reason is that there are so many possible causes of an idle problem, so it ends up being a common issue. The causes might vary, but most idle problems are caused by a mixture issue. It’s up to you to find the cause of the mixture issue. Once you do, I’m sure you’ll be able to get rid of that idle problem.

i am currently having this issue. 2003 honda crv 2.4 UK manufactory model. things ive tried, 1)purchased the $300 oem iac , 2) iac relearn procedure 2sec on then 3k rev for 10 without any load, 3) removed the ecu/pcm fuse for 5 min then replace and tried the relearn again, 4) check for vacuum leaks, 5)replaced the pcv incase this was the issue. i initially removed the old iac cleaned it and installed with no luck, this is why i bought a oem replacement. One thing i’ve noticed, when i erase the p0505 code with obd scanner, the crv idles perfect until driven and the check engine light comes back on. hopefully you may have some insight. thank you in advanced

Short and sweet 1993 Honda Accord CB seven. No modifications EX model. I am having the idle issue that is all so common where it fluctuates after it warms up a bit. I have a replaced the idler units in the front of the intake manifold and cleaned throttle body. check for water leaks and air leaks.With no avail. I have purged my water system. I have a video of me running the car and then putting my finger over the top hole in the throttlebody on the side closest to the firewall and idle drops and stays perfect. Does this mean I need to replace the throttle idle sensor?

I have a 2005 Silverado 1500 5.3l V8, recently when I am driving and I come to a stop light and im just sitting there in Drive, my battery gauge will move back and fourth and will have a slight rough idle to it when only the gauge is moving, the battery is brand new, what could it be? I know I have stuff plugged in to my 12v ports that I use, the battery gauge doesn’t drop below 14
