honda accord engine problem

Question:

I own a 99 honda accord. I don’t have problem with for almost 6 years. Today, when I started engine in parking position, I heard some strange noise, sounds like sudden accelerations, tachometer goes from 1000rmp to 2000rmp than drops back to 1000rmp, going back and forward. I thought something wrong with gas pedal. Then I drived it around, the engin noise grow louder. Does this indicate a big problem with the engine? Thanks, -James

Check the oil level, see if the rad is full, and the reservoir should be full to the line. Check back if anything isn’t where it should be. ‘Curly’

Response:

I agree check all the fluids levels first. I would also check airflow sensor which should be somewhere by the air filter and idle control sensor I am guessing by the air intake manifold. I can’t really give you good locations but I am sure you can find it fairly easy if you look up in manual. I own Honda now but my previous car had rough idle and rpm fluctuation, cleaning (very careful) airflow sensor with of "windex" and idle control sensor with contact cleaner solved the problem (all lot of carbon buildup). Good luck, hpe it helped

Response:

 Are you driving a modified honda?

Response:

No, it is not modified honda.

Response:

Thanks all of you, I followed your recommend. I found the problem and fixed it. It was the tube connecting the reservoir to the radiator loosing up, prevent coolant circulation. Now The engine runs smoothly again. Thanks again, -James
