99 Ford F150-Need Help!
Hey Everyone!
I could use some help I am getting a little frustrated with my truck. It is a 99 Ford F 150 4x4 5.4l. I am having power issues, it just never seems to have as much power as it use to. I have done a lot to it already...I replaced the fuel filter, air filter, changed plugs and COP wires. I took apart the Throttle Body and cleaned it out and that didn't seem to help either. I ran sea foam through the vaccum line that connects to the brake booster. (local mechanic recomended??) I have ran premium, put in fuel additives you name it. I also checked the vaccum pressure and it seemed in line with specs. I checked the fuel pressure and that seemed right along with specs to. I have checked for codes and got nothing. I did the KOEO test and the KOER test and nothing. The only thing on this that looked a little out of place was the calc load, at idle it was about 30% and just touching the throttle it would go to 50%. I am not even sure what to do or where to go from here. All help is greatly appreciated.
