I have a 92 Civic LX with auto and 138k miles. I've been noticing a bog, hesitation, lag, whatever you want to call it when taking off from a stop when the engine is at normal operating temp and AC is on. Outside temp is around 100. Removed and cleaned the EACV. Thought this fixed the problem until I drove in stop and go city traffic and it came back. What seemed strange after getting out of the traffic and driving non stop for a while the problem seemed to go away when I came to a stop and resumed. Temp related? Coolant level is fine. Starts right up in the morning, idles fine. Still gets great mpg. The only code I'm getting is a 17 that occurred during the winter and I will deal with later. The engine is stock.
