Question about 1983 Chevrolet Blazer
Anybody know anything about the TCS system on the 1983 Blazer? I'm changing the engine but am not replacing the emission control equipment. Will that affect the transmission's operation?
I heard that in most cases with the code PO44O it is just a "Loose" Gas Cap. You need to make sure the cap is turned until you hear several clicks. Then reset code and hopefully the light stays off.

More then likely its the Canister Purge Solenoid. you can find it online at www.autozone.com the part number is PV140. And to replace it on blazer you have to remove the spare tire. Alot of people don't know where this part is so I hope this helps you and good luck.

I had this probelm, we found that the throttle body gasket was letting air in through a tiny pin hole, new gasket fixed it. You have rebuilt yours, maybe check the seal. Be sure and use a new gasket.

The best thing to do is to buy a Chilton,s repair manual. It has step by step procedures. You can get one at most auto parts stores. They coast anywhere from $10-$30 dollars.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS, TPMS and BCM faults and others) as long as the light is on. You
must now have the dealer hook up a special electronic diagnostic tool
and "scan" the system for the fault code that is stored for

following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
problems. Also engine mechanical problems ca cause many
drive-ability related problem such as rough idle and other symptoms
