When I run my car and stop at stop light or sign. The engine kinda vibrates a lot. It started when I did tune up, changed spark plugs and fuel injection cleaning. I am guessing it is fuel injecton nozzel is gone bad. Do you guys can give me some input?

mine does that too sometimes... please let me know what it is when you find out. the shaking usually stops though when i come to a full stop. i'm thinking that maybe my volts are dropping when i stop and maybe causing the shudder. does it happen all the time?

You guys should try clean TB or raise idle rpm.
you can find out how on the FAQ.

man i got the same problem when i stop the stearign wheel vibrates a little and its staring to make me mad the stupid TB dosent do **** neither does rasing to idle your not posed to be rasing the idle its supposed to remain around 555 to 600 in gear so dont even tell people that.

bump i have similar issue

Well try to put on N when you're on stop.
the steering wheel won't shake.
and see where rpm needle is on.
mine's on around 700-750.
i think 555-600 is too low.
around 650-750 looks right.
I haven't fixed my issue also but I need to try raise idle rpm.

try this: get a can of carb cleaner and spray all around the intake (including manifold. if the rpms climb you have a leak in the intake. in other words more airs getting in than is supposed to causing the engine to run lean therefore causing misfire etc. etc.
