I have a 99 Accord, manual transmission. Over the past few months, about 4-5 times, while driving, the engine will be running smoothly and then lose power for a split second(RPMs will go down), but not turn off and then continue to run smoothly for a few more weeks until it happens again. Lately, when starting the car, it will seem to start (sound and RPMs) as I turn the key, but as soon as I turn the key back, it will die. After a few times of this, it will adventually start. I've tried changing spark plugs. Any thought about what it might be?

 

Faulty ignition switch.

 

^ agreed...I swear I just saw this post somewhere...oh well, I guess short term memory problems can be a blessing....but wait, I did.

To the OP, that is about four or five answers, all saying the same......good luck.

 

Thank you for your help-I'll try to replace the switch.

 

Does that have anything to do with the momentary lose of power while cruising? Are they 3 separate issues appearing at the same time?

 

There was a recall on the ignition switch on this Accord, back in maybe '02 or '03. Call the dealer with your VIN and ask if there are any open recalls on it.

If you end up doing it yourself, here is a good tutorial:

(pictures aren't showing up for me, I don't know if they are gone or if my internet security is blocking the host site)

 

Start with testing/replacing the switch, I'll bet the momentary lose of power while cruising will go away.....if not we'll need a little more detail about what you mean by that and the situation by which it happens.

 

these switches seem to be a common problem among accords are preludes this way to

 

That's a very good tutorial. I'll look into it this weekend. Thank you everyone for your help!

 

I called Honda, and they said that it was already replaced, but they can do it again! Yeah for Honda!
