Rough idle when weather gets warm
I know it sounds weird, but my '94 has a rough idle when the tepm ouside creeps up. Didn't have any idle problems during the winter. The car idles normally around 600rpm then jumps back and forth to 900rpm or so for a while then settles down. Also I have noticed it stumbeling at times under hard acceleratioin. I just had the transmission rebuilt so I know it's not that. I have a LT1 automatic. My guess it it's something computer related. Any thoughts ??

I'm leaning towards temp sensor....however you really need to scan it to see what's going on....you can have a sensor giving false info to the ecm and have it cause problems, but until the sensor completely fails it won't set a code.
