check my timing today and it was way off so i reset it at 16btdc . . .i noticed at idle the mark on the crank pulley was jumping back and forth about a 1/4 inch toward the TDC mark

any ideas? is my cam timing a tooth off?

BTW, its on 01 GSR

Did you jump the connector by the ECU and warm the car up before setting it?

yes.. car had been driven around for about an hour before i got my hands on it.. jumped the connector too

Was the idle bouncing around with the timing mark? If the idle was steady and the jumper on the service check connector had a solid connection, I'd check the cap and rotor. Corrosion on the terminals can cause slight fluctuations in the ignition. Aside from that, all I can think of is a bad connection somewhere.

idle was a steady 700-750rpm.. and CEL started blinking when i plugged it in.. codes are 22 and 45 .. oil pressure sensor and malfunction fuel system( too rich, too lean)
