Question about Cars & Trucks
Your car has a misfire on one or more cylinders. The flashing indicates the misfire is severe enough to damage the catalytic converter. After a short amount of time at a stable rpm, if the misfire continues at damage level, newer vehicles will disable the fuel on the affected cylinder(s) to prevent catalyst damage. The cylinders will then be "off" and the vehicle will shake and/or lose significant power (more power loss the more cylinders are shut down by the computer).
It is recommended you seek repairs as soon as possible, as each startup, the computer will re-enable all cylinders in the hope the problem has been corrected. If misfires are still present, the catalyst damage will again start up and continue until enough misfire measurement is recorded that the computer decides to shut off the cylinders (again). However repeated misfires in that initial phase will eventually cause permanent damage to the catalyst requiring expensive repair.

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.

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

You have a engine ignition miss, poss defective coil, get the trouble code out of memory to find out which cylinder is the problem, Kragen does the trouble code test for free.

the light is flashing to tell u that the engione has one or more engine cylinders misfiring, have the trouble codes tested to find out which cylinder(ws) is he problem.

EGR is stuck open, but a flashing engine light can be a misfire code also detecting a rich condition, right back to the egr.
