having problem with multiple engine misfire,very bad when engine is cold,once it warms up it runs fine, any ideas?

 

Could be all kinds of things. Did you do a code scan? Is there a check engine light?

 

Was checked with a basic OBD scanner and pulled a 300 code which is multiple engine misfire. I'm thinking it must be a sensor or some computer related problem...any idea's?

 

Could be a lot of things. I'd start by changing the plugs and wires.

From odb-codes.com:

A code P0300 may mean that one or more of the following has happened:

* Faulty spark plugs
or wires
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector(s)
* Burned exhaust valve
* Faulty catalytic converter(s)
* Stuck/blocked EGR valve / passages
* Faulty camshaft position sensor
* Defective computer
