i first want to say thanks for everyone that helped me with my problem....i changed the fuel filter, pcv valve, spark plugs, (8) COP, and the check engine has gone off and it seems to ride fine....but i am still having one problem....when im idleing in any gear it seems that the RPM's drop a little and the truck vibrates enough that you can feel it pretty easily, not as bad when the check engine light was on.....sorry to ask again....but does anyone have any ideas.....the thing is there is no more check engine light....work on the truck was done today and i only drove it for about 10-15 minutes so far......i was thinking to drive the car for a day or two to see if it goes away....thanks again everybody....ohhh by the way #4 COP was the error code coming up.....
