It starts and runs fine when it is below -15 degrees c but when it gets warmer outside it starts, then sputters and stalls. I have tried gas line antifreeze did not work. wondering if it is the fuel filter.

That's good preventative maintenance anyway plus rules it out but that probably isn't the up front problem. There's a coolant temp sensor AKA Engine temp sensor up near thermostat the tells the puter that the engine is cold and to deliver fuel accordingly. They are somewhat common BOTH the sensor and the wiring plug to it and both available. Sounds like your system is constantly delivering fuel based on being colder than it really is as it warms up. You can test the thing and decide if it's ok or perhaps if the plug doesn't look good go ahead and solder in a new connector. This is the common one for that vehicle - you didn't state which engine but same idea.... Fig. 5: Measure the resistance across the ECT terminals on the sensor Fig. 6: ECT sensor resistance value chart ******************** I'd focus on this for now. Don't wait forever to figure it out if not this as if it's flooding out engine all the time it's real hard on plugs and worse - the 02 sensors and converters, T Devbar New User Jan 23, 2009, 12:57 PM Post #3 of 5 (1770 views) Re: 1997 sunfire starts when it is below -15 but sputters and stalls when it is warmer out Sign In The resistance is where it should be on the chart. It runs fine even after it warms up on cold days. when it acts up it seems to be getting no fuel. It will idle but when you touch the gas it will stall. It will start again in a few minutes and stall again. Only on warmer days.

Are there any codes (SES on) or get it read anyway as there may be info there waiting to trigger the light, T Devbar New User Jan 26, 2009, 1:48 PM Post #5 of 5 (1748 views) Re: 1997 sunfire starts when it is below -15 but sputters and stalls when it is warmer out Sign In I took the car in and they said it was giving theft deterant system codes.
