Question about Nissan Sentra
I'm driving thru Minnesota on my way home to Ohio. I used about 1/2 to 3/4 of a tank of gas and my service engine light came on. I drive till close to empty and stop to fill up my tank. After filling up my car wouldn't start. My boy friend pushes the gas pedal to the floor as he turns the key and it finally starts. This is a 2007 Nissan Sentra, 4 cylinder.

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.

First place to check is the battery. Old ones can push your lights , radio, etc, but the starter is the real load. . Can verify this by using jumper cables to a running vehicle and watch your machine fire right up! The reason mornings are the worst, is the battery has had the most time to discharge, and it is probably cooler outside.

SOURCE: Gas Gauge not reading correctly
The most likely culprit is the sending unit in the tank. They are relatively easy to change, as long as you don't have much fuel in the tank. It's a mechanical unit that has a float that raises and lowers with the fuel level, however with age, the floats can develop leaks and no longer float, of the electronic portion of the unit can go bad and not register the proper level. They are replaced and an entire unit, so it doesn't matter which happened, you will need to change the fuel tank sending unit.
