OK so this is a problem since last winter. Once it gets cold the car has a hard time starting in the morning. Then spring/summer comes around and its fine. Now its winter again and every morning, and evening after work I go to start it and it turns over OK then right when it starts the RPMs dip real low and unless I juice the gas a few times it'll stall out. Then the other night it was REAL cold and it had a hard time starting at first, then got going and again I have to push the gas a bit. Any ideas?

It's not likely that's the source of the problem. I'd check the coolant and air temperature sensors that give feedback to the fuel injection system.Originally Posted by shaz

Their resistance changes with temperature, you can get the temp/resistance curves from a FSM or Haynes manual. Probably the coolant temp sensor. Test them by immersion in ice water and boiling water and cross referencing resistances.

yeah thats the only thing that makes me think maybe its not the TB...just that this is not a problem all year, only when its cold.Originally Posted by sweetdaddy

1) Clean your throttle body
2) Check your Engine Coolant Temperature Sensor
3) Check and adjust (if needed) the fast idle linkage. The fast idle plunger may also be frozen or broken. It's located down under the TB twards the left.
The Haynes manual can help you trouble shoot cold start conditions.

Air temp sensor has absolutely nothing to do with it, that thing doesn't seem to do anything actually...Originally Posted by sweetdaddy

Doesnt the air temp sensor attribute to the fuel mixture ratio when running lean versus rich?Originally Posted by ivelweyz
