Why does my 2001 CRV stall out after it sits overnight
Asked by Motiger Nov 01, 2012 at 10:48 AM about the 2001 Honda CR-V LX AWD
Question type: Maintenance & Repair
The car stalls out and won't idle after sitting overnight. I have changed the plugs, fuel filter, MAP sensor, Throttle position sensor, and cleaned the IACV which was clean to begin with.. 96,000 miles and a good vehicle. initial check engine code indicated throttle position sensor and Map sensor.. I am stuck with taking this to Honda

But it idles fine when warm? This would indicate an open loop problem which means only a few sensors are responsible for engine operation and most are running on a factory "preset". Seeing a map and TPS code, maybe there is a vacuum leak. Have the vacuum checked.
make sure the throttle blade is closeing all the way as well. Sorry for the double post.
Yes. the vehicle runs fine once it is warmed up.. How do I check for a vacuum leak..
Get a vacuum gauge would be a sure fire way, find a vacuum hose. Brake booster hose works great. And see what it reads. Without a gauge you can listen for hissing, spray some starting fluid where you hear the hissing. If the idle changes when you spray it there is a vacuum leak there. Still check the throttle body to see if the throttle blade is closeing all the way and not gunked up. If it hangs open even the tiniest bit it will casue low vacuum (map code) and the tps wont sense closed (tps code).
Thx for quick response I will check hoses and the throttle body.. would probably just spray simple lubricate wd40 on it and work it so it closes 100%..
