I have a 95 civic ex I just filled my car up yesterday and now it keeps dying while I'm driving down the road I thought it might be water in the gas so I put some heet in the gas tank but it still does it I don't know what wrong with it help me please

Go over the ignition system, paying particular attention to the condition of the spark plugs (NGK only), spark plug wires, rotor, distributor cap, Ignition Control Module (ICM), and coil. Ignition Control Modules and, to some extent, coils are problematic on Hondas. Heat tends to affect them with age. I recommend that they be replaced every 120,000 miles or 10 years, whichever comes first. Here's how to replace the ICM and coil:

AutoZone will test ICMs and coils for free. Here's what the ICM looks like and costs:

If this doesn't solve the problem, go through the steps outlined in sections A and B below:

Make sure your fuel filter has been changed in the last 60,000 miles or 4 years.

You could have some very bad gas. I filled up once on the Mass turnpike and couldn't get out of the station! But you could have a coil breaking down. Will the car idle at all?

My car has ran fine to this point it will idle just fine I have after market coil and this. Cap new plugs and wires

Some cars will idle okay with a marginal fuel filter but will quit at highway speeds, when it prevents the engine from getting all the fuel it needs. This has happened several times on my father's Toyota pickup truck.

It is possible the aftermarket coil could still be faulty, even though new. If the car will idle but won't respond under light throttle, the coil doesn't have enough to fire through the fuel mixture. This is a common problem. There are test that can be done, if you can get your car to a facility that has that test equipment.

Even still, fuel additives take some time to make any difference. The additives have to move through the entire system until they arrive at the injectors before you'll notice any change. And with your car being sooo good, economically, that'll take a while... sorry...

If you can get a fuell sample, in a clear bottle, let it set for a while and see if any separation occures. The water will settle to the bottom (some will be normal, but not much)
