Re: Couple questions, Timing Advance and Fuel Trims

Still getting readings no higher than -10 advance (short happening), tried with KS unhooked no change (no code either), tried unplugging the Cam and Crank sensors and still NG, also no code (didnt run long maybe about a minute.)

Checked fuel pressure for kicks. At Idle 38PSI, crack the throttle open and pretty much the same (maybe 40PSI). Pull the vac line off the FPR and 45PSI is the reading. Suddenly close the throttle from a certian RPM and the pressure bottoms out at 35PSI.
