Lately it feels like my car is losing power(hp) around 20 or more. I'm pretty sure it's a fuel issue,but everytime I hook the f/p guage up to it,it runs perfect. I'm not sure if it would be the pump,injectors, or regulator.Has anyone had a problem like this or heard of something like it.

 

are you checking FP while under load? or just at idle/revving?

 

under load

 

Leave the gauge connected, problem solved

 

ok one more ques.
Blue: blinker and brake light, red:tag lights and the arrows are where the wires intersect
I know you can't see very well, but I need a little help. The right blinker and brake light doesn't work and I cant tell if it would be a break in the wire,but as I was reading the diagram I got to thinking that it might be because both of the tag light were blown but I'm not sure.Can anyone correct me?

 

I would run my own ground to the problem bulbs and see if they operate or check for voltage going to them with a test light.

Ill try to find a wiring diagram and post more info for you later

 

they have a ground,the tail light works but brake light and blinker doesn't(this is on an expedition btw) it has 3 wires:ground,minor(tail light),and major(blinker and brake)

 

so trace the power side and see where the power is being lost

 

so it turns out I was right,there is definintely something wrong with my car just not sure as to what it is. I went to the track today and ran slower than an auto covertible. my first run was a 15.74 @ 89, 2nd run:16.03 @ 86 3rd run:16.02 @ 85 i'll have a vid in a little while
