FUEL PRESSURE REGULATOR

[docc]

WT:

 

Try setting every thing up at a higher idle RPM. The tach may be reading "low." Do a full TPS / throttle body balance at 1300 RPM indicated on the tach. Open your "air bypass screws" to one full turn.

 

Just my Bad-2-cents!

 

Good luck! docc

Now idle stop screw of right hand throttle body is fully back off.

Should I touch this screw any more? Or let it be backed off?
