hello
1. when i rev the engine, car stationary, after releasing the pedal most of the times rpm drops to 0 and then goes up again to idle, or the engine just stalls. if i rev it from the throttle, after i release it i hear a click sound from the fuse box area.
with a/c on, sometimes the engine hesitates from idle.
any ideas what's wrong?

2. the crankshaft pulley looks wobbly when the engine runs, here's a little video i took.
should i bother to remove the pulley and re-install it or install a spare one?

 

It is hard to tell from the video if the crank pulley is wobbling or if it is just the engine shaking.

Did you do any work on the car before you started experiencing this problem?

A simple test for the pulley is to draw a radius line on the pulley face from the bolt to an edge. Drive the car and get it to act up. Shut off the engine and see if you still have a straight line. That pulley has a rubber piece that can separate causing the crank part to spin, but the outside part holding the belt may not spin.

 

if you refer to the pulley then no.

 

I meant any work at all on the car not long before experiencing this problem.

 

the only thing that may be relevant to the engine stalls is new air cleaner element and intake hose, all genuine honda.
i got the car only 3 months so i don't know how long these problems exit.

 

The crankshaft will have some lateral movement, so that wobble may be normal. If you look closely at the crank pulley, there rubber between the inner metal and outer metal. Mark a white-out line then drive for a bit to see if the rubber is still holding the inner&outer metal pieces together. It is an easy test to try.

I'd probably disconnect the battery and clean all ends of both battery cables with a wire brush or sandpaper.

I would expect a bad crank pulley to give you problems all the time and not just on a warm start-up.

You should stop by an autoparts store and have them scan for codes. Post any codes on here. You can also have them test the battery and alternator to make sure they are working properly.

 

i want to buy my own diagnostic scanner, any recommendations?
since mine is a 00 japanese built i was told i need a honda specific device.

 

Not sure I remember from another thread - you're in Israel?

If you were in US, I'd say that it doesn't matter where it's built. It matters what market it's built FOR. Made in US, made in Canada, made in Japan, made in UK, if it's built FOR the US then it'll have a compliant OBD-2 system and you can choose from a lot of scanners that are readily available in the US.

I don't know how that works for cars that are built for sale in Europe or Middle-East or whatever region. It's probably not specific to Israel, but I don't know what region (for carmaker laws) you fall into.

 

Agreed. My Japan built 99 Accord was built to US specs, just like my wife's 2000 Ohio built Accord. I use the same scan tool on both.

But like Jim mentioned above, I don't know where Israel falls as for which country the scan tool would work.
