i have a 93 sc manual w/260,000 miles on it. when the engine gets to normal operating temp, it loses some power, i have new o2 sensors, intake and exahaust, and i have no codes running, i have no ideas left, any suggestions please. thanks
 
It probably runs better cold because the computer supplies more fuel. With 260K miles, it's most likely time for a rebuild.

David, I read something once about the ECC restricting power in hot weather, or something like that... is it true? Does the ECC do anything drastically different when it’s hot out?
