My engine is vibrating when you start to run, all

I have a 92 Nissan that had this same problem. 1st I would have a tune up done on it. If that does not work you will have to have the fuel injectors replaced on the car as I had to do. If you are going to replace the fuel injectors make sure you replace them all. Because when one starts going they are all about at the end of there life.

Good Luck
