hello, is truck running ok -- or does the light just come on in the morning when cold?
it start running bad and then when the light goes out it runs ok
this light is for the throttlebody-- on this particular year -- I have seen this light come on for two different reasons-- one would be the throttlebody and the second would be valve springs-- does the check engine light come on when throttle light comes on
and does it do this only when cold?
we have also seen quite a few of these do this when MAP sensor fails -- It would be a great help to have the computer scanned(engine controller) and see if we are getting any fault codes
