When I start it up the engine knocks/pecks for a while until the temp gague gets to almost mid way between hot and cold. it has 102,000 miles on it. Any suggestions??? I don't know if this may be a lifter or what.
Thanks.

 

What size or liter is your engine?

4.7L Engine

 

I would use Seafoam to clean the throttle body, use better grade of gas, and tune-up the engine to see if that clears up the problem,

I had read in a previous post about the manafold studs, could that be a possibility?

 

This seems to be a common problem with the 4.7L. It can not hurt to look at them,
