That is good.
Fuel pressure is not your problem.

Re: 4.3 Engine problem

I started checking a few other things and believe my MAP sensor was reading about .5 to 1 volt lower then it should at idle. Installed a new MAP and I am just going to run it for a while, we will see if it goes through plugs again. Is there any other way to know if I am running lean?
