can someone please list all the reasons why my car dies on start on days with temperature from 38 to 45 F. I dont think its the battery or starter problem because it tries to crank up all right. The throttle body is clean. The air filter is brand new condition. The fuel filter was change 10k miles back. However my front left heated O2 sensor is bad. Could it be that problem?

 

my car does the same thing... 100k miles. what is up? Come to think of it, my old 300zx used to do that also... kinda
Anybody have any ideas???

 

I had a similar problem not too long ago. I replaced the battery and that didn't solve the problem, so i ended up going to the dealership. They hooked it up to their diagnostic machine and said the idle was low. They raised the idle and the problem was solved.

Hope this helps.

 

Yeah most likely your idle is below 500 rpms... did you mess with your throttle cables on your throttle body?... did you add any mods prior to having this problem?... Should try to figure out how it happened.. maybe some how your throttle cable has gotten loose, go check the screws that tighten them..

 

yeah and replace your o2 sensor... the front ones are important :-)
