If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring. Leave a comment below or tell us if the information above help you fix the code.
I am guessing that one of the ambient air temperature sensors may be bad. Also, if it were the sensor, where would I find it if I wanted to replace it myself and is it an easy job?
I can't really say whether you need a new crate motor or not (haven't they heard of rebuilt engines? I guess the question now is how much do you want spend. This is when the outside temps are actually around 75-80 degrees.
I suspect that you had a minor issue and the extra load on the engine (towing) caused whatever it is to finally fail. Lately, my interior temperature gauge has been showing the outside temperature as being anywhere from around 0 degrees to -10 degrees.
Considering two technicians have already seen the vehicle up close and done thier own diagnosis, I'm not sure I'll be able to be of much more help. You didn't say how many miles are on the Chevy, but given it's nearly 10 years old and the symptoms I'm going to guess the miles are starting to get up there. Perhaps you need a third opinion, but I suspect that's not going to be much help either. Maybe you should get the codes read again and then look them up. Question: I have a 2004 Chevy Trailblazer EXT 6 cylinder.

Since the code refers to the circuit, simply buying and replacing the oxygen sensor won't definitely fix the code.
The code is set because there is a problem with that oxygen sensor heater circuit.
