Re: 2.8 problems
Reset the ECM to clear the codes.
Drive it normally and keep the speeds down for a couple of days. Pay attention to how it runs.
Just curious to see if everything is normal with normal driving.
I'm going to guess that 85 is getting close to pushing the limits of fuel pressure supply versus actual demand.
Stock PSI is about 9psi.
Repsonse is much better across the board when closer to 13 psi, but to do this, retuning of the tables in the prom are required.
Oh, don't pay attention to the "guys at autozone" and what they say, especially crap like that.
That's why they work at autozone....idiots....
