I know a lot of people like to throw around the big 10 number but you should not be dissapointed when you realize it will take 10-15k+ to make a 10 second streetable sn95. But you can make a really fun to drive 12 second 4.6 L for only a couple thousand if that interested you. I dont want to be...

Im unsure if your fuel rail pressure sensor is the same as the gt but i ruined the diaphram inside the frps and it caused my car to die and run terrible. i was told when the diaphram is ruptured in the frps high fuel pressure spikes will kill the car because the sensor does not read correct. The...

When i turn my key to the on position i can hear my fuel pump kick on but my fuel pressure reads 0 at the rail. The car then fires right up and the pressure jumps to 28. I read that fuel pressure should be steady at 30psi at idle is this correct and is 28psi an exceptable number?

Hi all my car for the past month or two has had a sputter when driving at low rpms. The last few days the low rpm stutter has smoothed out and the car now bogs and sputters really bad at anything over 3000 rpm. The car will not drive at highway speeds anymore it just sputters and stalls. The car...

I have been struggling with the hanging rpms for months and drives me absolutely crazy and am not happy with what i have like you mentioned. as soon as i get the chance i will be trying the IAC mod and setting the throttle body blade. I would have never thought it to be coils but have heard...
