i need help (smoking/runs rough)

[dr_erni]

this truck just seems to keep on getting worse the longer i own it heheh...

it started doing this recently...

after it warms up and everything... it still smokes out of the left side (looking from the back forward) the smoke doesn't seem to stay a certain color, sometimes blue, sometimes white, sometimes it doesn't smoke at all...

When i'm at a stop in gear, it idles pretty rough and takes off rough also.

Could you give me some pointers, other then "take it to the junkyard"

thanx
