  1. Okay thanks to everyone for all the ideas and directions to go. We found our issue, and it is once again it is a case of "Start with the Basics" We did a compression check and found that each cylinder was at 125-150. However, we didn't do a running compression check before the head gaskets. We found that a lobe on the cam was worn and this was causing the valve to operate improperly. Thus valves were causing the popping. Meaning replace with used engine or rebuild. Thanks everyone.
  2. Thank you for the information. I have not had a chance to look at it further this last week. I am hoping to record the engine running condition and try a few of the suggestions I have been given over the last week. Thanks.
  3. I don't usually get stumped, so I am assuming this must be out of my skill set. 2002 Ford Taurus 3.0 (U) SES - Replaced the Fuel Pump and Filter (poor pressure), Plugs (Fouled white debris - lean condition), Coil (Misfiring - no CEL or Codes), Battery (shorted cell). It will start, sputter, misfire and run like it is out of time and die. After holding throttle at 1800 rpm for 2 minutes (many misfires, coughs, sputtering and intense fuel smell) the only codes are (Catalytic Converters checked and are empty): P1131 HO2S11 (Heated O2 Right Upstream) not switching correctly, Sensor indicates Lean P1151 HO2S11 (Heated O2 Left Upstream) switch Sensor indicates Lean P1400 DPFE Sensor circuit Low Voltage I haven't had a Taurus not run/idle without codes to indicate a direction to go in that a coil didn't fix. Curious on where to go next (I am familiar with GM, not so much Ford. Have Maxisys Pro Scanner and Snap-On Verus D10 w/ 4 channel lab scope, no subscription to perform most tests). Greatly appreciate any insight, Thanks.
