Message	Today when setting the timing I Noticed that the PTU and Coil pack readings were not the same. While using an ECU monitoring Program, I set the timing to the value shown, in this case 20*. Decided to check the reading at the PTU Loop as well, and found the PTU was showing 10* more than the coil pack. Has anyone else ever had this problem and/or know how to repair it? My understanding is both locations should be the same. Also, noticed the timing when read from the ECU would never drop to 15*. TPS = 0.46V Coolant Temp = 190*F Thanks, Jason

Is your idle speed correct? - aliaZ 17:28:37 11/05/12 Yes, the idle switch is on and functioning correctly. - alpha_omega16 11:33:40 11/06/12 The ECU expects 15 degrees, not 20 - aliaZ 23:29:18 11/07/12 Agreed... timing light is the only way!!
