Surely someone out there has a thought on this. You guys have always jumped in to help problem solve...

Last week I replaced the front O2 sensor to solve a p0125 with intermittent rough idle that I thought was narrowed down to that sensor. Ran great for several days, idled great, good MPG, no codes. Now the truck is throwing a p0130 and is idling a little rough again. When the front sensor is...

Sorry for the delay. It actually came out pretty simple. The brass nipple that actually threads in is hollow for the wires and a small flathead screwdriver turned it out with a little patience. Must have over-tightened on install...

I put in a new coolant temp sensor about a week ago and within a few days started getting the typical sensor code. I figured the sensor must be a bad unit and bought a replacement under warranty. Boy was it a bad unit! It is broken off so that no easy access to remove it. Where the threads...

According to the FSM the valve should move in or out depending on the order that you apply ground to the terminals.

Alright, I pulled the IAC again to test, based on a hunch. Using the FSM, I tested the unit and may have my problem. The valve does not move forward or backward. I can hear the solenoid trying to engage, but no movement. Can these be rebuilt or do I start digging for a used one?

Would faulty o2 sensor readings lead to poor idle only a low temp and eventually a no start condition. I am pretty good with a wrench and a lot of tools but understanding the intricate connections between all the sensors is not my strength.

I am now at a no start condition. I have checked for fuel pressure -good- and checked all sensor connections -good-. It will try to fire but only for a millisecond. I cannot get enough fire to register any codes. I pulled the negative battery cable over night and reconnected this morning and...

Is there a simple way to test the IAC, or is it a matter of taking the unit off and following the FSM diagnosis...

So I just started it in the cold and is started normal for a second, with the rpms kicking up to about 1500. It then quickly dropped rpms, and did the jumping gauge again. I am wondering if this is an indication that the IAC works instantaneously but is not holding the TB open long enough to...

Just ran some obd diagnostics and here are some measurements. Short term fuel trim 0.0, long term fuel trim 19.5, TP% 8.2, B1S1 0.035, B1S2 0.125, Fuel sys 1 OL_Fault. Does any of this help? Coolant temp sensor did not help...

From my understanding the o2 sensors should be on hold until normal temp is reached.
