My 00 camaro shakes really bad first thing in morning when I start it but it's fine after it gets to operating temp

Any thoughts would help

 

Are you talking about a shaking while it sits still (engine) or while you are driving (wheel)?

 

sitting still at a idle I can (play) with the throttle and it stop

 

Sounds like its misfiring or running rough. Check your plugs and wires and see if any look bad.

 

yea I was standing outside of the car an is sounded awful...plugs are new....only thing I don't get is it only does it on the first start after that is fine an it doesn't have a misfire code

 

check plugs to see if one cylinder is running rich. you may have a leaky injector. check fuel pressure and make sure the pressure regulator is working.

 

If you have replaced the plugs, THE FIRST THING to check is the sparkplug wires. If one one crossed(not plugged to correct plug), it will cause the rough idle you're experiencing. I had the same thing happening after having some work done to mine. If that isn't the case, proceed with the other suggested solutions.

 

Make sure your plug wires aren't old and arcing either. Just start the car in the dark and look for sparks arcing off the wires to metal.

 

how can I check to see if I have a leaky injector and if the fuel regulator is working properly

 

Check your fuel pressure with a gauge while the car is running. If fuel is leaking you will probably smell it too.
