Think about the valves. If they are to tight (Valve clearance) with the heat added when warm, they (Or one) might not close. I'd check there first.

Chevrolet Caviler 2.4 - 2000 Stalls at idle (stopped) once car is fully heated up.


Check coolant temp sensor. These fail often and cause all kinds of mystery problems. This unit acts much like a choke on old carb engines and can fail in different ways. Most common (I think) they fail such that the ECU thinks the engine is cold when it has begun to warm and thus the ECU delivers too long a pulse to the injectors so that the engine runs way too rich. I think it is also possible for the sensor to fail at any point between cold and warm such that the fuel mix is wrong except for the particular temp at which the sensor is stuck. Also O2 sensor has some fuel "trim" input.

If you haven't done it already you might have them run it for codes to see if it is showing any. Autozone does it for free too.

My 05 crf 450r will not idle when I turn off the choke it also is backfiring and poping when I give it gas . Could it have something to do with the hot start cable ?


Check your pilot jet is not blocked or try adjusting your idle screw for the idle issue and it sounds like its runing lean which can also make it idle low and rough and will cause it to pop and backfire. Dont think it has anything to do with your hot start cable that will make it run it run better if its running rich but your is doing the opposite

When staring from cold it is neccesary to use full choke but the bike struggles to stay running, backfiring and quiting. It is also neccesary to keep the throtttle slightly open as the engine will die if...


Has this 6 year old machine ever had a top-end job done? If not, then you may want to consider it. You can just replace the rings but I'd at least pull the cylinder apart and check for blow-by or a stuck ring. if your rings don't rotate freely in their channels, then it's time to replace them. If your cylinder has a glassy look to the inside walls, then it needs a hone job at a minimum. Kustom-kraft.com is an excellent choice for top-end service.. Bikebandit.com is THE place for parts.

I recommended you to check the air filter and clean it as well and also tune your air-fuel ratio to 9:1. This will workout but if it still continues then get service by an authorized personal.
