I noticed today my 94 f150's check engine light went on yesterday and again this morning. I have never seen this light come on. The temperature here was 32below yesterday and this morning. I went on a whim to the gas station and filled one of my tanks with gas line antifreeze and since then I have not noticed the light. Is it possible to have the light come on if the engine is not getting proper fuel flow due to freeze up. I am travelling 250km tommorow and hopeing the engine wont quit on me or something. I live in remote BC we do not have auto zones or anything like that around here. Thanks.
