Code 23 in your 1993 Chevy Blazer is referring to the Manifold Air temp sensor being out of range. Start by looking for the sensor to see if it is unplugged.
Trouble code P0135 means:O2 sensor heater circuit malfunction (Bank 1 Sensor 1)
Trouble code P0325 means:Knock sensor 1 circuit malfunction
ESC / Electronic Spark Controll Circuit. and the knock sensor signal.
Trouble code P0144 means:O2 sensor circuit high voltage(Bank 1 Sensor 3)
Trouble code P0186 means: Fuel Temperature Sensor B Circuit Range/Performance

I have a code DTC P0154.Bank 2 Sensor 1 no activity.Which sensor is this on my 96 Blazer?
it a transmission slipping code
it could be your fuel regulator .it wont set a code on this if it is going out
If it had a bad O2 sensor the "check engine" would be illuminated and a code would be set indicating which sensor is at fault. You probably have other problems causing that backfire to occur.
call the dealer and get the code....
Was that the only code that caused you to replace it? Do you have it close enough to sense again.
low pressure on you MAP sensor clean it or replace it
Code p0507 2001 chevy s10 replace upper intake, iac, tps still have problem
I have the check engine light on and the code is for map sensor on my 1999 1500 Chevy suburban
I've got a better question, why is this question in the Chevy venture forum ?
System to rich (bank 2)
O2 sensor heater circuit malfunction (bank 2 sensor 1). This is the O2 sensor located in the header pipe directly after the exhaust manifold on the passenger side of the 4.3L engine. If the wiring to that sensor looks okay, more than likely that sensor needs to be replaced.
There is actually a little bit more info needed: 2WD OR 4WD, Ring Gear size, 7-5/8 or 8-1/2, What ratio? GM option code: GU4-3.08 GU6-3.42 GT4-3.73. However It wont be a direct fit to a 2000 blazer only 1995-1997 Blazer only. For 1997 makes a difference with or with out AWD, along with with or with out ZR2 option.
Trouble code P0339 means: Crankshaft position sensor "A" circuit intermittent
I just bought this blazer and it only came with one key my dad had the same year blazer and it had keyless entry
