My car sputters when I drive.?

Question

I start my car and it sputters. Then When I push the acclerator it feels like it wants to go but kind of sputters again anyon eknow what it might be.

Answer 1

Depends on the car. If it is an older car with a carb it is probably bad. If it has injectors they might be dirty run some injector cleaner throw the system. Do a tune up and change out fuel filter and air filter. If it still has this problem than your heads are bad and need repairs.

Answer 2

Either a misfire or an o2 sensor issue. The first guy is correct. You can't ignore a check engine light. That sputtering is either misfire or detonation (suggesting o2 sensor problem.) If the code was emissions related, then I'm gonna say it's a bad o2 sensor. What's probably happening is the bad sensor is telling the computer that the engine needs more fuel, which won't all get burnt. This is giving the same effect as a misfire. Your o2 sensor controls the air/fuel ratio. If it's bad, you will have problems, and it will lead to a clogged catalytic converter

Answer 3

You don't really tell us much. We really need more information to be able to really offer you and real HELP.
Otherwise, this is pretty well reduced to the Karnak method diagnostics, and we all know how effective and satisfying that can be.

"Check Engine" light on?
Only cold or all the time?
How long has it been doing this?

And you girls get annoyed with us because we "…won't communicate meaningfully"! ;>)

Answer 4

It's really hard to answer your question without some background on the car first. My question back to you would be when was the last time the car had a tune-up.

Answer 5

Start with plug wires first. If you have over a 100,000 miles on you vehicle it is time to change your plug wires.Talk with your local mechanic and find out what else is recommended at the mileage you are at

Answer 6

fuel filter, plug wires bad

could be your brakes
