The check engine light flashes is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

SOURCE: Shaking and service engine light

This sounds like it could be one of several things. What have you done as far as your last tune up? A bad spark plug or wire could do this and it is a simple fix for the shaking. The major problem could be your Timing. The Timing might be off. Your timing and your spark plugs have a lot to do with each other. You mention this happens when you put it in drive. Then you mention shifting gears. Most Nissan's are stick shift. Is your car a stick or manual transmission? When was the last time that you checked or changed your transmission fluid?

On an automatic Transmission.
You have to check your transmission fluid with the car running. You should change your transmission fluid and filter around every 10,000 miles, but nobody ever does this. You need to get some Lucas for transmissions to go in it and it will help a lot if it is jerking. Parts stores know what this is.

This could also be a sensor going bad. If you have a parts store in your area, you can take it to them to run a diagnostic on it. If you take it to a garage, it could cast anywhere from $100 to $200 for them to do the same test. Autozone in my area does this test for free. Some other parts stores do them, but I do not know about your area. The big problem with the sensors is that the test might not tell you the exact sensor that is bad. The best thing to do is to have the parts store run the free test for you. Then if it is the plugs and or wires, buy a set of NGK plugs for your car and a lifetime set of wires. (Bad plugs and wires can show up as a sensor sometimes.) Then you will need to reset the service engine light, so you will know if the problem is fixed. To do this you can sometimes unhook your battery for a few minutes to reset the computer. If that does not reset the engine computer, the parts store that did the test can reset it for you. Try the cheapest thing first which is the plugs and wires. Also change your transmission fluid and filter. If you have not changed your oil in the last 3,000 mile you need to change your oil and use Lucas oil additive along with Castrol motor oil. If you live in a climate where it does not get over 80 degrees you can use 10w40. If it gets over 80 degrees you need to use 20w50. (Some places and people are using 5w30, but this is mainly for brand new cars without any leaks or burning oil.) The Lucas will protect your engine and make it run smooth. Lucas is great stuff for any engine new or old. It is cheaper to buy it by the Gallon, if you are going to use it a lot. It is the best thing for an old engine. You can use up to 2 quarts of it in an engine and I have heard of people using more than that.

Ask me more questions if you need to. That is what I am here for. Do not rate this right away unless you are satisfied.
If this solves your problem rate it as a Fixya not a helpful or thanks for trying.

SOURCE: car is jerking engine light is flashing and smell gas

With modern cars it is bad when the engine light just comes on and the vehicle does something very different. It should not be driven. If the car is smelling of fuel and jerking it is because it's miss-firing (i.e. one or more cylinder is not getting spark but is getting fuel). This can be anything from electrical/electronic to mechanical like a broken rotor cap (as an example). The good thing, is that the light is coming on and a mechanic can check the ECU for error codes. Alternatively, you can buy or barrow one your self and check it out on your own (I think even certain auto-part stores will check it for you as long as you get in the zone;). 1996 is a good year for that since that is when OBDII started and all vehicles started using the same port to check for issues.

You need to have a computerised car diagnostic done to the car.This will tell you the error code and what is causing this problem.Remember to always reset the car if there has been any replacement parts.Hope this helps.

1999 Nissan Sentra 1.6L sets p0304 code


check that your spark plug wires are all secured tight. the far right cylinder is giving you the issue, cylinder #4. Is the engine light flashing while the car is running? if it isnt flashing, then its a past code and isnt misfiring anymore. if the engine light is flashing, you either have a bad plug wire, or a bad ignition coil/distributor.

Replaced computer in 2002 sentra,car wont start now


I assume the car was running before you replaced the computer. If you still have the old computer try it on. This will help you determine if the problem isn't in the new computer. If you can't test as above, check for power to the distributor. If no power then check the circuit from the computer to the distributor (first the fuses that are marked "Engine Control" then the wires at the connector on both ends). If the circuit is OK then the computer is probably faulty.
If you get power then check the coil pack or the distributor. I don't have the wiring diagram for the 2002 Sentra but usually power to the pump is controlled by the distributor.Please feel free to let me know if I can help you more.

My 04 Nissan sentra starts up fine. Then about 5 minutes down the road when I stop, it won't accelerate again until I turn the car off for a minute and restart. If I let off the gas too much it stops...


Take your car to a local parts store, they will read the engine code for you for free. They will also offer possible actions  fix it and parts it will take. Be careful out there.

I HAVE A NISSAN d21 2.4L 1987 hardbody pick up as im driving when i let up on the gas pedal it seems to stumble just a little bit then it seems fine after that ???


Sounds like it could be faulty fuel injectors. (unless of course, it's carburated, then it'd be a poorly adjusted float)

I use nissan sentra 2002 my service engine soon is on for 2weeks


Finding out what the code number is, is the first step.

You can find this easily by watching the blinking yellow check engine light and counting the number of flashes for each of the numbers in the 4 digit fault code.

To do this without a code reader; sit in the car and turn the ignition on (do not start the car) and after 3 seconds push the accelerator pedal all the way down to the floor and release fully (pull your floor mat out from under the gas pedal). After the 3 seconds, do this 5 times quickly, in less than 5 seconds. Then hold the accelerator pedal down for exactly 7 seconds and release it fully. Then within 10 seconds, the yellow check engine light will begin to blink.

The numbers of blinks will go from 1 to 10. A 10 will represent a "0".

For example; 0303 would be 1st number is 10 flashes, short pause then 3 flashes, short pause then 10 flashes, short pause and 3 flashes. It will repeat this again if there is only one fault code. There could be other fault codes and you would count those in the same way.

The 0303 code means that you have a cylinder misfire in the #3 cylinder. This could be a fouled plug, poor connection between the plug and the coil or something else.

To erase the code hold the gas pedal down while the yellow light is blinking for about 15 seconds then turn off the ingnition. Code will now be reset and light will go out.

If for some reason you do not get the yellow light to start blinking, tturn off the ignition and try it again. You may wish to get a watch with a second hand as the time is critical as to the seconds between steps.

After you find out what codes you have, send back an email and we can document the actual codes and the problems you are having.
