When driving the motor pings under the least of load, check timing , no vacuum leaks , not real sure what it the problem is . I thought about buying new MAP sensor but when I went to get one, it looks a lot different than the one on the truck now. Any help would be great , thank you for your time and help.

If it has just started may be a bad batch of fuel, are there any set fault codes? check regardless if no check light is on.

Normally a carbon build up problem or a timing problem, you may need to see if the distributor advance is working.
