I have accord 2005 L4, threre is a problem during the parking and on the way.

when on parking mode, the RPM gauge drops suddenly and some times causes the engine to shutdown.

when driving, at any speed except while the RPM on high and the speed is 200 and above, I noticed that there is something hold the car and speed drops suddenly then accelerates the drops then accelerate and so on.

Honda comapany in my region tried to find the problem, but unfortunately they did not find the exact problem. they have changed everything related to this problem like, throttle body, fuel pump, fuel filter, spare plugs, air filter, some electric wirings until they replcaed the computer itslef, but still the problem presist.

What is the problem do you think? and what is the solution??


Please, I need your help if someone faced the same problem.

Your problem may be caused by a recurring and intermittent electrical problem with the fuse/relay/multiplexer. The multiplexer is part of the fuse/relay box on your gen Accord and is replaced as a unit. There was a recall on certain VINs; but, even if your VIN was not listed, I would think this may be causing your problem since the other things you listed were already replaced.

I do agree with redbull that it is the problem with the fuse or the multiplexer.
