Hello everyone,

I have a 1992 Honda Civic Hatchback with a 1999 engine with a cold air intake and 1999 transmission.

When I start the engine, it revs 2500 then slowy up to 3200, and then it drops down to around 2300 and rev up to 3200. It keeps doing that every seconde. The engine overheat, when I turn the heat on, it doesn't blow the heat out of the engine. It sounds like the engine is seaching for something.

I chane the oil, anti freeze and the thermostat. The dash board doesn't indicate anything.

Anyone knows what is the problem?

No need to make a double post. Already started in the 96-00 section. Please don't make duplicate threads.

Sorry about that.
