Incomplete monitors :catalyst 2004 envoy emmisions fail ?
After the MIL is turned off or the battery was disconnected for some time, all monitors are set to incomplete. However with several short trips with engine getting at least to hot enough for thermostat to open, (I believe 8 is the magic number of trips) most monitors are set, you may be able to pass the test with only one incomplete only.

2005 GMC ENVOY 4.2L. I have a P0740 code on it?
DTC P0740 Torque Converter Clutch (TCC) Enable Solenoid Control Circuit
Circuit Description
The torque converter clutch (TCC) solenoid valve is an electrical device that is used with the torque converter clutch pulse width modulation (TCC PWM) solenoid valve in order to control TCC apply and release. The TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. The TCC solenoid valve receives ignition voltage through the ignition 0 voltage circuit. The powertrain control module (PCM) controls the solenoid by providing the ground path on the TCC solenoid valve control circuit. The PCM monitors the throttle position sensor voltage, the vehicle speed, and other inputs in order to determine when to energize the TCC solenoid valve.
When the PCM detects a continuous open, short to ground or short to power in the TCC solenoid valve circuit, then DTC P0740 sets. DTC P0740 is a type B DTC.

What is the cylinder order in a 2003 gmc envoy
1-5-3-6-2-4 I'm going to completely assume that the GMC envoy, based on what I can gather, uses the old 235 Chevy (50's) design, since it reduced balance issues, and therefore, this would be the right sequence.
