What causes a car to sputter and idle rough on my 1994 Honda civic lx?

Answer 1

That is not normal. There are many things that could be causing that problem. The easiest and cheapest thing you could do is to replace the fuel filter. Usually they will run just a few bucks at the local auto store. If that doesn't do the trick, try to see if your car is smoking at all and try to determine if it is blue, black, or white smoke. Usually a blue smoke is oil, black is usually fuel richness, and white is coolant. White and blue are the most serious. If you are just burning extra fuel, you might need a tuneup consisting of new sparkplugs, maybe new sparkplug wires, new distributer cap, and distributor rotor. This might be a good time the change the oil and oil filter as well as check the other fluids such as transmission, coolant, and brake.

AnswerIf the engine dies whenever it is warm and low rmps chances are your ignition coil has an intermittently trouble. Check for primary and secondary circuit resistance. AnswerDon't forget the possibility of a bad o2 censor. They can cause all kinds of problems not the least of wich a very rough idle, and sputtering especially at stops. Good luck AnswerFrist determine if your engine has fuel injection or carbs .. if the latter it could be a vacuum leak , burnt valves , plugs need cleaning and gaping, a plug wire short to ground or the distributor cap or coil shorting..

If this is a late model car it could be the O2 sensor front, rear, both, also a bad fuel injector could be the problem, also a vacuum leak will cause the problem but normally it's never that simple. Also check your gas cap...

Do you know what could be causing this problem. AnswerIn some cases an emissions service at you local dealer can solve a number of problems, from sputtering from a stop, to very poor fule mileage. It wirked for us on our 1998 Chevy Prizm
