Try this first:
1. Start car (have someone sit inside to hold idle if need be), but let the car idle on its own if possible. (replace fuel filter before anything, it is usually located on the driver side, just behind the rear tire.)
(see step three before doing step 2) 2. You will want to locate the MAS, Mass AirFlow Sensor. This is on the air intake. Find your air filter, and follow it toward the intake (center of engine). About a quarter of the way up, you'll see a small black rectangular box. With a screwdriver handle, or other small, lightweight tool, tap on the sensor. If the engine fluctuates, or dies, it needs replaced. If not, it may only need to be cleaned. You can purchase MAS cleaner at the auto parts store. Follow the direction on the back of the can. If this does not fix the problem, then replace the sensor.
3. If the MAS does not fix it, and the idle is still rough, check the distributor cap and rotor (if equipped), as well as the coil wire (center of distributor cap, follow to coil). If the rotor looks warn, is white with build up, as well as the points on the inside of the cap, replace them both, as well as the plugs and wires.
4. If step three does not work, proceed with step 2.
Please let me know if you need further assistance.

My 1998 Honda Accord 4Dr LX has lost power.

I'd check the fuel filter. ($8- 20) it's easier to remove with a toggle joint socket adapter. It's part of regular maintenance, so if it doesn't fix your issue, it's not a waste of money.

I have a 4 cilinder Honda Accord 1998, today for the first time the engine light swithced on and the "D4" light started blinking at the same time that the "D3" light was on (the gear setting I was in at...

D4 light on means transmission fault of some sort. Have the vehicle scanned as soon as possible, because it might be a minor glitch, and the transmission could be saved. Have in mind that these transmissions (1998-2002)are notoriously prone to fail around 60-80000 miles. If rebuilt with the remedial kit (i dont remember the proper name for this), the transmission tends to work normally.

My 1998 honda accord check engine light Is on. And there are two p codes 1259 and 1456. how to fix?

Fuel filler cap is loose. 1456

Tighten *at least SIX* clicks. Wait three engine on-off cycles. Light
should go off.

If it does not go off, the cap may not fit tightly enough for a proper
seal. Replace cap. Occasionally, the threads in the filler necks can be
damaged, preventing the cap from being properly tightened.

Code 1259 is vtec system malfunction, in other words, it's a variable valve timing and lift electronic control. It's honda's system used to control the rate of engine valves to open and close. Need to take it to a shop or dealer to have that checked out.

98 Honda Accord LX CODE 1259

Code 1259 indicates a V-tec system malfuntion assuming your Honda isn't a DX? Disconnect the negative battery cable so that you can clear the code. If code returns, try cleaning and/or replacing the V-tec pressure sensor. I heard of someone that had the same 4000 rpm problem you speak of and this is where they solved their problem. Good luck to you.
