Revs up and down problems

Top problems

Starts but won't reach more than 3,000 revolutions

Honda Accord 2000  264410 miles
Suddenly my car stopped speeding up, and cannot go beyond 3000 rpm. I've cleaned the throttle body but it remains the same... revolutions go up and down but nothing more than 3000 rpm, what can it be?

Hi, Melly. I had the same problem and the cause was located in the engine's belts. There are two of them, a huge and a little one, check over there.

@YahyaThere is two separate screens one on the vtec in the back of the motor and one behind the belt tensioner that could be clogged as well. People tend to clean the easy one but they forget about the hard one. That would set off the same code as give the same symptoms as the vtec.

I have an Honda Accord 93 and many times, but not always, when I start the engine revolutions go up and down continuously. Even more, sometimes after driving it for a while it chokes but does not stall. As I speed it up it chokes even more. Only after some time it gains enough strength.
